Feature Showcase App Guide

Jessie Cheah edited this page Jul 18, 2024 · 6 revisions

Tip

A newer version of the Guide is also available, separated into 6 files. Please refer to README.

Tips on how to use this Guide:

When you see a feature that you would like to implement, copy or take note of the search term (e.g., #SearchTermExample) and perform a search here. You will be presented with

  • a short description of the feature,
  • code snippets and where to find them in the source code,
  • and in some cases, a link to the official RAP documentation for more information.

💡 Take note that the links will always lead you to the RAP documentation for the latest release! You have to take into account the version of the system you have.

Alternatively, you can search for an annotation here, get the search term, and use it to locate the UI feature in the app. If the annotation cannot be found, it could simply mean that it is not showcased in the current release.

General Features

Using IANA Timezones

Search term: #IANATimezone

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

With the annotation @Semantics.timeZone you can convert a timezone to one specified according to the IANA standard. You are also able to assign this converted timezone to a timestamp (which has to be in the UTC format) so that the time will be interpreted in this timezone. The annotation to use is @Semantics.timeZoneReference.

The conversion of the timezone is happening at the backend, while the timestamp conversion is done by the UI.

This feature is also available for use with action/function parameters.

In the following example, changing the SAPTimezone field will also change IANATimezone and IANATimestamp, which are both shown in IANA standard and changing Timestamp will change IANATimestamp automatically. This is achieved via side effect.

Value Help

Search term: #ValueHelps, #DependentFilter

The implementation of a value help in CDS enables the end user to choose values from a predefined list for input fields on a user interface.

The additional binding defines a second condition for the value help on the same target value help provider entity for filtering the value help result list and/or returning values from the selected value help record. The additional binding can be defined for an additional element or parameter. Depending on the value provided in usage, the additional binding works as a filter, result or filter and result condition

Usage: #Result: The referenced element or parameter in localElement or localParameter is filled with the value provided by the value help. When creating an instance, you can fill various fields with this option.

Note

Source: CDS View /DMO/FSA_R_RootTP

// Search Term #ValueHelps
@Consumption.valueHelpDefinition: [
  { 
    entity: { name: '/DMO/FSA_I_Criticality', element: 'Code' },
    additionalBinding: [{ element: 'Name', 
                          localElement: 'FieldWithCriticality', 
                          usage: #RESULT }] 
  }
]
CriticalityCode,

Usage: #Filter : The value of the referenced element or parameter in localElement or localParameter is used as a filter for the value help. The value help only displays filtered results.

// Search Term #DependentFilter
@Consumption.valueHelpDefinition: [
  { 
    entity: { name: '/DMO/FSA_I_Contact', element: 'ID' },
              label: 'Contacts',
              additionalBinding: [{ element: 'Country',
                                    localElement: 'Country',
                                    usage: #FILTER }] 
  }
]
ContactID,

You can influence what is shown in the value help using @Consumption.valueHelpDefault.display. In the example below, everything except for ID (Name), phone, country, street, city and postcode would be hidden in the value help.

Note

define view entity /DMO/FSA_I_Contact
...
{
      @ObjectModel.text.element: ['Name'] // Search Term #DisplayTextAndID
      @UI.textArrangement: #TEXT_ONLY
      @EndUserText.label: 'Contact'
  key id            as ID,

      @Consumption.valueHelpDefault.display:false 
      name          as Name,

      @Consumption.valueHelpDefault.display:true 
      phone         as Phone,

      @Consumption.valueHelpDefault.display:false 
      building      as Building,

      @Consumption.valueHelpDefault.display:true 
      country       as Country,

      @Consumption.valueHelpDefault.display:true 
      street        as Street,

      @Consumption.valueHelpDefault.display:true 
      city          as City,

      @Consumption.valueHelpDefault.display:true 
      postcode      as Postcode,

      @Consumption.valueHelpDefault.display:false 
      address_label as AddressLabel,

      @Consumption.valueHelpDefault.display:false 
      photo_url     as PhotoUrl,
      ...
}

For smaller collections of possible values in the value help, it might be a good idea to have a dropdown instead of a dialog to choose the value. This can be achieved with the @ObjectModel : { resultSet.sizeCategory: #XS }

Note

useForValidation

Search term: #useForValidationVH

Warning

Only shown in the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

To mark a value help as an input validator, one can use the keyword useForValidation: true in the annotation @Consumption.valueHelpDefinition. It can be annotated at a field, a CDS parameter or an action parameter.

It is good practice to use the keyword qualifier for every value help, even if the field only has one. If you have defined more than one value help at a field, useForValidation might not work correctly if you have forgotten to use qualifiers, as UI would not be able to determine which value help is to be used for validation.

This keyword does not work for collective value helps.

💡 If you have a draft-enabled app, using this annotation prevents an invalid value from being saved to draft. A refresh of the page will clear the user input.

💡 Another alternative to this annotation would be to use a drop down list with @ObjectModel : { resultSet.sizeCategory: #XS }, if there are not too many available choices.

Note

Source: CDS View /DMO/FSA_R_RootTP

// Search Term #useForValidationVH
@Consumption.valueHelpDefinition: [{  entity: { name: 'I_RegionVH', element: 'Region' },

Feature Control

Static Feature Control

Search term: #StaticFeatureCtrl

Each field can have specific access restrictions, defined in the behaviour definition. If the access restriction is always the same for each instance, you can use static feature control. Some examples/possible combinations are described here:

Note

Source: Behaviour Definition /DMO/FSA_R_RootTP

define behavior for /DMO/FSA_R_RootTP alias Root
...
{
  field ( readonly, numbering : managed ) ID;
  field ( mandatory ) Email;
  field ( mandatory : create, readonly : update ) StringProperty;
}

readonly

There are 2 different types of readonly:

field ( readonly, numbering : managed ) ID; means that the field ID is a key that will be assigned a value by the framework (numering:managed) and must not be created or updated by the user at all (readonly). The annotation in $metadata is <Annotation Term="SAP__core.Computed"/>.

field ( mandatory : create, readonly : update ) StringProperty; means that the field StringProperty is only mandatory during create, but after that it will be read only. The annotation for the readonly in $metadata is <Annotation Term="SAP__core.Immutable"/>.

mandatory

field ( mandatory ) Email; means that the user must provide a value for the field Email. The annotation in $metadata is <Annotation Term="SAP__common.FieldControl" EnumMember="SAP__common.FieldControlType/Mandatory"/>.

More Information: ABAP RESTful Application Programming Model - Static Feature Control


Dynamic Feature Control

Field

Each field can have specific access restrictions, defined in the behaviour definition and behaviour implementation. If the access restriction depends on a certain condition, you can implement the feature control dynamically.

Note

Source: Behaviour Definition /DMO/FSA_R_RootTP

define behavior for /DMO/FSA_R_RootTP alias Root
...
{
  field ( features : instance ) TimesChildCreated;
}

Note

Source: Behaviour Implementation /DMO/FSA_BP_R_ROOTTP

METHOD get_instance_features.
  result = VALUE #( FOR root IN roots
                      ( %tky = root-%tky
                        %field-TimesChildCreated        = if_abap_behv=>fc-f-read_only
                      ) ).
ENDMETHOD.

In this simple example, the field TimesChildCreated is dynamically assigned the restriction read-only.

The annotation in $metadata is <Annotation Term="SAP__common.FieldControl" Path="__FieldControl/TimesChildCreated"/>.


Operations and Actions

For dynamic control of operations and actions, the option (features: instance) must be added to the operation or action.

Note

Source: Behaviour Definition /DMO/FSA_R_RootTP

define behavior for /DMO/FSA_R_RootTP alias Root
...
{
  delete (features : instance);
  action ( features : instance ) changeProgress parameter /DMO/FSA_D_ChangeProgressP result [1] $self;

METHOD get_instance_features.
  READ ENTITIES OF /DMO/FSA_R_RootTP IN LOCAL MODE
    ENTITY Root
      FIELDS ( UpdateHidden DeleteHidden ) WITH CORRESPONDING #( keys )

    FAILED failed.

  result = VALUE #( FOR root IN roots
                      ( %tky                    = root-%tky
                        %delete                 = COND #( WHEN root-DeleteHidden  = abap_true
                                                            THEN if_abap_behv=>fc-o-disabled
                                                            ELSE if_abap_behv=>fc-o-enabled  )
                        %action-changeProgress  = COND #( WHEN root-UpdateHidden  = abap_true
                                                            THEN if_abap_behv=>fc-o-disabled
                                                            ELSE if_abap_behv=>fc-o-enabled )
                        ) ).
ENDMETHOD.

The delete operation and action ChangeProgress will be disabled if the fields DeleteHidden or UpdateHidden has boolean value abap_true, and vice-versa.

Actions

Datafield ForAction

An action that is defined via Datafield ForAction is not tied to a specific data value. Therefore it is possible to assign the annotation to any arbitary element. Whether the action button is to be in the list report or object page, line item or section, this largely depends on the respective UI annotation you use. More examples are listed below in this guide, if you search for action.

The keyword to use for this is type: #FOR_ACTION in @UI.lineItem, @UI.fieldGroup, etc.

Datafield WithAction

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

An action that is tied to a data value, which would be rendered as a hyperlink. Therefore it is crucial to specify the annotation at the desired element which has the data value. Whether the action button is to be in the list report or object page, line item or section, this largely depends on the respective UI annotation you use.

The keyword to use for this is type: #WITH_ACTION in @UI.lineItem, @UI.fieldGroup, @UI.identification.

More Information:


Value Help for action parameter

Search term: #ValueHelpParameter

Often properties of an entity have value helps, so that creating a new entity is easier and wrong inputs are reduced. Value helps for action parameters are also possible.

Note

// Search Term #ValueHelpParameter
@Consumption.valueHelpDefinition: [{ entity: { name: '/DMO/FSA_I_Criticality',  element: 'Code' }}]

This can be achieved, by just annotating the parameter with @Consumption.valueHelpDefinition.


Default Value for action parameter

Search term: #ParameterDefaultValue

With the annotation @UI.defaultValue a default value for the parameter is set. A fixed string value can be given or a property from the entity can be reference using syntax #( 'ELEMENT_OF_REFERENCED_ENTITY: <field_name>' ).

Warning

Only shown in the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

An action parameter now inherits the text label from the underlying data element. No additional effort is required other than maintaining the label (and localized text label) at the data element itself. For comparison, see the examples below.

Label from data element:

Using IANA Timezone in Action Parameter

Search term: #IANATimezoneAParameter

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

With the annotation @Semantics.timeZone you can convert a timezone to one specified according to the IANA standard. You are also able to assign this converted timezone to a timestamp (which has to be in the UTC format) so that the time will be interpreted in this timezone. The annotation to use is @Semantics.timeZoneReference.

The conversion of the timezone is happening at the backend, while the timestamp conversion is done by the UI.

This feature is also available for general use.

In the following example, the action overwriteTimezone expects a timezone input. Choosing a value using the value help will fill in the IANA Timezone as well.

It is possible to define mandatory parameters for action/functions but to do this, you would need a behaviour definition for the abstract entity. This is typically a deep parameter with a hierarchy structure but instead of a true hierarchy with associations, we define the abstract entity as a flat structure.

In this example, the field sap_timezone should be a mandatory parameter and will be marked with a red asterisk (*) . The keyword to use is mandatory:execute, to be marked at the field in the behaviour definition.

Note

Source: Abstract Entity /DMO/FSA_D_OverwriteTimezoneP

Default Values Function

Search term: #DefaultFunctionForCreate, #DefaultFunctionForAction, #DefaultFunctionForCBA

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release.

With a default values function you can default the input parameters for actions, functions, as well as create and create-by-association operations, similar to the annotation @UI.defaultValue (see Default Value for action parameter). The difference here is, with default values function you can specify the values using more complicated coding.

The general rules are:

  • Function name must begin with GetDefaultsFor
  • Function name must be unique within the current BDEF
  • In certain cases, external names can be given
  • Key word is {default function GetDefaultsForxxx;} behind the respective operation

The importing parameter and the return type of the function need not be specified, as they will be derived by the framework from the respective actions/operations. If you have a projection layer, it is necessary to expose the default values function too in the projection BDEF.

create

In this example, the property StringProperty, which is a mandatory input for create, will be prefilled with the value Default Value for Root Create.

Further rules:

  • Function name after the keyword default function is optional. When specified it must be GetDefaultsForCreate
  • External name is not possible

create-by-association

In this example, the property StringProperty, which is a mandatory input for Child create, will be prefilled with the value Default Value for Child Create. Property FieldWithPercent will also be prefilled to avoid triggering a validation error when saving (this is not shown in the pop up during create, but the code can be found in the behaviour implementation).

Further rules:

  • default function must be specified in combination with create within curly brackets for an association.
  • External name is possible

Recommended Data Types

Search term: #RecommendedDataTypesSection

To define the data model of our business object, we have to create tables to store the data that the CDS view is built upon. For the backend to derive the correct data types for oData, there is a list of recommended, released built in ABAP types and data elements that you can use. There are used in the app and can be seen in the Object Page under Data Types(#RecommendedDataTypesSection).

Setting up QuickView

Search term: #QuickView

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

A quick view is a pop up that shows more information, when you click on an entry in a column or an object page. Typically, it is used in combination with one-to-one or zero-to-one associations. By clicking on the link, more information about the associated entity can be displayed.

To enable a quick view facet, the association entity needs to be annotated with @UI.facet with type: #QUICK_VIEW. For a better looking header of the quick view, the association entity gets typically annotated with @UI.headerInfo. Additionally, the key value can be replaced with another text property using @ObjectModel.text.element, so that the column is readable.

Note

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

When your associated entity (QuickView entity) has a key that is non-UUID, a referential constraint for the association does not get generated automatically. To do so, a property needs to act as a null value indicator for the QuickView property, similar to a value control property, using the annotation @Semantics.nullValueIndicatorFor.

Note

Source: CDS View /DMO/FSA_I_Root

define view entity /DMO/FSA_I_Root
  ...
  association [0..1] to /DMO/FSA_I_Criticality as _Criticality  on  $projection.CriticalityCode = _Criticality.Code
{

  @ObjectModel.foreignKey.association: '_Criticality'

  // Search Term #QuickViewNullValueIndicator
  @Semantics.nullValueIndicatorFor: 'CriticalityCode'
  cast(' ' as abap_boolean preserving type ) as CriticalityNullValInd, // Null value indicator

  ...
}

Then setup your QuickView entity as usual.

AdaptationHidden

Search term: UI.adaptationHidden

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release.

Important

UI Adaptation is only possible with deployed apps. Therefore some features of this annotation cannot be showcased in the Feature Showcase App app preview, unless stated otherwise.

UI adaptation is a feature of SAPUI5 flexibility that allows key users without technical knowledge to easily make UI changes for all users of an app, end users to personalize controls, and developers to extend the UIs of SAPUI5 applications. For more information, see SAPUI5 Flexibility: Adapting UIs Made Easy.

But there are some scenarios where you do not want to allow this, that a specific property or entity should only adher to the metadata or annotations. It is possible to do this, by using the annotation @UI.adaptationHidden: true.

Only Applicable for Deployed Apps

As a result, the property Description cannot

  • be removed or added in, in the object page
  • have its label/description be edited
  • have its position on the object page be changed via drag-and-drop

Visible Also in App Preview

In addition to the above, the property Description cannot

  • be added in as a list report filter

Note

Source: Metadata Extension /DMO/FSA_C_RootTP

CDS Simple Type

Search term: #SimpleType

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release.

Simple types allow the definition of user-defined scalar types together with (arbitrary) domain-specific metadata via CDS annotations.

Simpler put, you can create user-defined data types in ABAP CDS, which work similarly to Data Elements in DDIC. The advantages of CDS simple types are:

  • you can type them to build-in data types like abap.int4, DDIC data elements, or even other CDS simple types
  • you can use a fixed list of CDS annotations to enrich the metadata of these data types, including but not limited to: EndUserText, Semantics, and others

Tip

To get the full list of allowed annotations in simple type, simply use Code Completion in ADT with Ctrl + Space after typing @

These data types can be used in CDS views by view parameters directly, or by properties via casting, and also directly by parameters in abstract entities. You can also use them in your ABAP code, especially when you are developing the behaviour implementation of RAP business objects.

Warning

Do not use CDS Simple Type with enumeration as it is not supported in RAP. CDS Simple Type is not supported in classic DDIC like tables and structures

Creating Simple Type

Note

@EndUserText.quickinfo: 'Radial Integer Value'
@EndUserText.heading: 'Radial Integer'

// Search Term #SimpleType

define type /DMO/FSA_BT_RadialInteger: /DMO/FSA_BT_Integer

The simple types /DMO/FSA_BT_ProgressInteger and /DMO/FSA_BT_RadialInteger are typed to another simple type, otherwise known as stacking. The types will also inherit the annotations of the base type, or they can be overwritten, as is the case here.

Using Simple Type

Note

Source: CDS View /DMO/FSA_I_Root

define view entity /DMO/FSA_I_Root...
{
  ...
  cast ( integer_value as /DMO/FSA_BT_Integer preserving type ) as IntegerValue, // Search Term #SimpleType
}

Note

Source: CDS View /DMO/FSA_R_RootTP

define root view entity /DMO/FSA_R_RootTP...

Note

Source: Abstract Entity /DMO/FSA_D_ChangeProgressP

define abstract entity /DMO/FSA_D_ChangeProgressP
{
  progress : /DMO/FSA_BT_ProgressInteger; // Search Term #SimpleType

Configuring Tables

To see columns in your table, you would first have to define them with the annotation @UI.lineItem at the property, either in the CDS view or in a metadata extension. The most basic setting you can use would be:

  • the order of the column in the table and
  • changing the column label, if you do not want to use the label from underlying views.

In the example below, StringProperty would be the second column in the table (the numbering used here is 10, 20, etc. You could also start with 1, 2, etc. ), defined using position. label would be the column label/heading.

importance denotes the importance of the property. With #HIGH, this means that the property will always be shown even if the table is rendered on a small display.

Note

Source: Metadata Extension /DMO/FSA_C_RootTP

@UI.lineItem: [
  {

Copy Action in Line Item

Search term: #CopyActionInLineItem

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

For a deep copy of an instance, the RAP framework does not provide a copy action out of the box, unlike create/edit/delete. However you can define a factory action in the BDEF that copies an instance, and by using the keyword isCopyAction: true, the action button will be rendered in UI harmoniously with Create/Delete. When no label is provided, it is automatically set to 'Copy'.

The cardinality of a factory action is always [1], that means, only one instance can be copied at a time.

When used in conjunction with inline: true to render the Copy button at individual line items, a label must be provided by you.

Navigation Button

Search term: #Navigation-IBN

An action navigating to a published app of an associated entity can be added, through Intent Based Navigation using @UI.lineItem. When the navigation is setup properly, a button will be rendered at the table toolbar. Since this feature requires Fiori Launchpad and a destination app that has been published, the following is just an example of how it can be coded, as this navigation does not work in a FE App Preview.

Here "FeatureShowcaseNavigation" is the semantic object to be referenced.

Adding a Smart Micro Chart to a Table

Bullet Micro Chart - Table

Search term: #BulletMicroChartTable

To add a bullet micro chart to a table you have to first define a data point at the property where the value is to be taken from, which is the actual bar. The following attributes are also mandatory: minimumValue to render the chart properly, forecastValue for the bar in the background with a lower opacity, targetValue (or targetValueElement) for the dark line and qualifier (qualifier must be set to the name of the property). Criticality is optional.

To show the chart, the property must then be annotated with @UI.lineItem.

      @Semantics.address.zipCode: true
      postcode      as Postcode,

      @Semantics.address.label: true
      address_label as AddressLabel
}

To show the contact card in the table you need to annotate the contact property with @UI.lineItem or if in a facet, with @UI.fieldGroup.

Note

Time and Date

Search term: #TimeAndDate

SAP Fiori Elements provides out of the box support for displaying and editing dates and times, as well as time stamps. No additional annotations are needed, the properties just need to have the corresponding data types.

The following annotations are used in the app, in order to group the time and date fields and show them in a facet.

Note

// Search Term #TimeAndDate
@UI.facet: [
  {

Collective Value Help

Search term: #CollectiveValueHelp

For SAP GUI-based applications it is possible to define a collective search help that combines several elementary search helps. You can choose one of several alternative search paths and retrieve input values from multiple sources/tables in a single dialog. In Fiori UI this is also possible via a collective value help using an abstract entity comprising a list of assigned elementary search helps and potential mappings of the bound field names.

The collective value help shall be annotated with @ObjectModel.collectiveValueHelp.for.element pointing to the field, for which the collective value help is defined. The field referenced by @ObjectModel.collectiveValueHelp.for.element shall be assigned at least a single elementary value help using annotation @Consumption.valueHelpDefinition.

Only the following keywords can be used for a collective value help: entity.name, entity.element, additionalBinding.localElement, additionalBinding.element and qualifier.

Note

Source: CDS Abstract Entity /DMO/FSA_D_CountryCVH

@EndUserText.label: 'Country Collective Value Help'
@ObjectModel.supportedCapabilities:[#COLLECTIVE_VALUE_HELP]
@ObjectModel.modelingPattern:#COLLECTIVE_VALUE_HELP
@ObjectModel.collectiveValueHelp.for.element: 'Country'

// Search Term #CollectiveValueHelp
define abstract entity /DMO/FSA_D_CountryCVH
{
  @Consumption.valueHelpDefinition:[
    // 'Default' VH
    { 
      entity: { name:'I_Country' },
      label: 'Search by Country' 
    },
    // additional VH, set qualifier
    { 
      entity: { name:'/DMO/FSA_I_ContactVH',
                element:'Country' },
      label: 'Search by Contact',
      qualifier: 'ContactSearch' 
    },
    // additional VH, set qualifier
    { 
      entity: { name:'I_RegionVH',
                element:'Country' },
      additionalBinding: [{ localElement:'Region',
                            element:'Region'  }],
      label: 'Search by Region',
      qualifier:  'RegionSearch' 
    }
  ]
  Country : land1;
  Region  : regio;
}

The consumer view of the collective value help has to define the same fields, that are used in the collective value help definition (respectively bind all corresponding local fields via @Consumption.valueHelpDefinition.additionalBinding... to the collective value help fields).

Side Effects

Search term: #SideEffects, #SideEffectsSection

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

Side Effects annotations specify to the UI, which targets to be refreshed in order to show updated values that arises from field changes, actions, or determine actions. Side effects are defined in the behaviour definition. There are a variety of ways to annotate side effects by combining the triggers and the affected components, and a few examples are shown in the app:

Warning

If you use projection, remember to add the following to your projection behaviour definition.

projection...

use side effects;
define behavior for ProjectionView {
}

Field affects field

Fields from same level entity

When the user changes the value of IntegerValue, the determination setIntegerValue is called and modifies the values of ProgressIntegerValue and RadialIntegerValue. In order for these 2 fields to show the updated values without a refresh, side effects is required to request UI to reload these 2 fields.

Note

Source: Behaviour Definition /DMO/FSA_R_RootTP

define behavior for /DMO/FSA_R_RootTP alias Root
...
{
  determination setIntegerValue on modify { field IntegerValue; }

  side effects {
    field IntegerValue affects field ProgressIntegerValue, field RadialIntegerValue;
  }
}

Fields from associated entity

It is also possible to define as target, a field from an assoicated entity. When the field ChildPieces in Child entity is modified, this will trigger the determination calculateTotalPieces to total up the pieces of all child instances. Side effects will trigger the refresh of field TotalPieces from the Root entity to show the calculated total every time user enters a value at the child instance.

Entity affects field (workaround)

When an instance of an associated entity is deleted, a field should be updated. While there is no dedicated syntax to cater for this use case, this can be achieved with a workaround by defining a determination that is always called by a determine action, with side effect defined for the determine action.

In our example, updating ChildPieces at the associated entity _Child will update the field TotalPieces of the Root entity.

Data Points

Rating

Search term: #DataPointRating

To add a rating indicator (stars) to the object page header, you first need to define a datapoint with @UI.dataPoint. The property where datapoint is defined sets how many stars are visible. Values between x.25 and x.74 are displayed as a half star. The attribute targetValue defines how many stars are possible. Most importantly, the qualifier needs to match the property name.

Note

Source: Metadata Extension /DMO/FSA_C_RootTP

@UI: { 
  // Search Term #DataPointRating, #DataPointRatingTable
  dataPoint: {
    qualifier: 'StarsValue',
    targetValue: 4,
    visualization: #RATING,
    title: 'Rating Indicator (#DataPointRating)'
  }
}
StarsValue;

After creating the data point, it has to be added to the @UI.facet annotation.

@UI.facet: [
  {
    // Search Term #DataPointRating
    purpose: #HEADER, // or #STANDARD
    type       : #DATAPOINT_REFERENCE,

Progress

Search term: #DataPointProgress

To add a progress indicator to the object page header, you first need to define a datapoint with @UI.dataPoint. The property where datapoint is defined sets the current progress and the attribute targetValue, the maximum progress. Additionally, a criticality can be given, if wanted. Most importantly, the qualifier needs to match the property name.

Note

// Search Term #DataPointProgress, #DataPointProgressTable
@UI: {
  dataPoint: {
    qualifier: 'ProgressIntegerValue',
    targetValue: 100,
    visualization: #PROGRESS,
    criticality: 'CriticalityCode',
    title: 'Progress Indicator (#DataPointProgress)'
  }
}
ProgressIntegerValue;

After creating the data point, it has to be added to the @UI.facet annotation.

@UI.facet: [
  {
    // Search Term #DataPointProgress
    purpose: #HEADER, // or #STANDARD
    type       : #DATAPOINT_REFERENCE,
    targetQualifier: 'ProgressIntegerValue'
  }
]

Micro Chart Facet

The following micro charts are supported: Area, Bullet, Radial, Column, Line, Harvey, Stacked bar and Comparison. Micro charts can only be displayed in the header.

A micro chart is defined with the @UI.chart annotation, which then is the target of a ReferenceFacet in the @UI.facet of purpose: #HEADER. The title of the facet is the attribute title of the annotation and the subtitle is description. If the property of the data point is a property with unit of measure, the unit will be displayed in the footer. The attribute measures of the chart has to be a data point.

The @UI.dataPoint supports generally the attributes criticality and criticalityCalculation, but the support varies between the micro chart types. If the value of the data point is annotated with a unit of measure, the unit will be shown as the footer of the micro chart facet.

In the following examples, all used attributes are mandatory.


Area Micro Chart

Search term: #AreaMicroChart

The area micro chart is a trend chart, which provides information for the actual and target value for a specified dimension. The displayed values at the bottom of the chart are the boundary values of the dimension. The values above the chart are the boundary values of the measure attribute.

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

For a deep copy of an instance, the RAP framework does not provide a copy action out of the box, unlike create/edit/delete. However you can define a factory action in the BDEF that copies an instance, and by using the keyword isCopyAction: true, the action button will be rendered in UI harmoniously with Edit/Delete.

The cardinality of a factory action is always [1], that means, only one instance can be copied at a time.

When no label is provided, it is automatically set to 'Copy'.

Large Object/Stream Property

Search term: #Stream

You can enable your RAP application for maintaining large objects (LOBs). By doing so, you provide end users the option to incorporate external binary files or text files when editing entity instances. First the appropriate fields should be added into the database table and the CDS view, and also the annotations @Semantics.largeObject and @Semantics.mimeType. To show it in a standard or header facet, you will need annotation @UI.facet. Lastly, you should also update the mapping and the draft table in your behaviour definition.

RAP Treeview for Hierarchy

Search term: #RAPTreeview, #RAPTreeviewSection

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release.

ABAP CDS allows for the structuring of data in hierarchies. For RAP, it is possible to display this CDS Hierarchy as a readonly treeview in the SAP Fiori UI, either as a list report which has a different implementation (an example can be found in ABAP RESTful Application Programming Model: Implementing Treeviews) or in the object page, which will be described hereafter.

The example implemented here represents a file folder system. Each folder has a parent folder, which is itself a 'normal' folder, and the topmost/root folder does not have a parent. Each folder is named with a combination of colour and number, and the name is used to sort the hiearchy. The root entity will serve as a 'directory' so that each instance has its own hierarchy which can be displayed in the object page.

To implement this you would need the following artifacts:

An underlying database table

The root_id contains the id of the directory, in this case the root instance. parent_folder contains the folder_id of the parent.

Note

Source: Database table /DMO/FSA_FLDR_A

define table /dmo/fsa_fldr_a {

  key client    : abap.clnt not null;
  key root_id   : sysuuid_x16 not null;
  key folder_id : sysuuid_c22 not null;
  parent_folder : sysuuid_c22;
  folder_name   : abap.char(1024);
  folder_size   : abap.dec(10,2);

}

A CDS view which represents the database table

It serves as the source for the hierarchy, has a self-association and an association to the root entity, the directory. Annotations depicting how the treeview is shown in UI is also declared here. The most important annotation, @OData.hierarchy.recursiveHierarchy is required to specify the hierarchy.

Note

      @EndUserText.label : 'Size of Folder (in GB)'
      folder_size   as FolderSize,
      _Directory,
      _ParentFolder
}

The hierarchy

The source of the hierarchy is /DMO/FSA_I_Folder. The parent of a node is defined via association _ParentFolder, which is a self-association. The hierarchy is filtered with parameter P_Directory, which is the ID of the root instance so that the correct hierarchy is shown in the object page of the instance. The topmost node is the one with an initial ParentFolder and the hierarchy is sorted by FolderName.

Note

Source: CDS View /DMO/FSA_I_FolderHN

define hierarchy /DMO/FSA_I_FolderHN
  with parameters
    P_Directory : sysuuid_x16
    
  as parent child hierarchy (
    source /DMO/FSA_I_Folder
    
    child to parent association _ParentFolder
    
    directory _Directory filter by
      RootId = $parameters.P_Directory
    
    start where ParentFolder is initial
    
    siblings order by FolderName
  )
{
    key RootId,
    key FolderId,
        ParentFolder
    
}

The following artifacts must be modified:

CDS View /DMO/FSA_I_Root, /DMO/FSA_R_RootTP and /DMO/FSA_C_RootTP

An association to the hierarchy must be included in the root entity, since the root entity serves as a directory. The association _Folder need to be exposed up until the consumption view /DMO/FSA_C_RootTP.

  typeNamePlural: 'Root Entities (#OPTableTitle)', // Search Term #OPTableTitle
  ...
}

If the section title and the table title are identical or the @UI.headerInfo annotation is not given, the table title will not be displayed. Also if the table is the only content in a subsection and has a title, the subsections title will not be displayed.


Action Overload in Object Page Tables

Search term: #ActionOverload

Warning

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.

Action overload means to add an action bound to another entity, to the object page list table of a child entity. The action is defined in the behaviour definition, and the UI annotation to add the action is defined in the other entity's CDS view or metadata extension.

The example given here, is an action button displayed at the Child entity table in section Child Entity (1..n)(#OPTable), that calls a Root action to create a new Child instance.

Note

Source: Behaviour Definition /DMO/FSA_C_RootTP

define behavior for /DMO/FSA_C_RootTP alias Root
{
  action ( features : instance ) createChildFromRoot result [0..1] entity /DMO/FSA_C_ChildTP;
}

Note

// Search Term #ActionOverload
@UI.lineItem: [
  { 
    type: #FOR_ACTION, 
    dataAction: '/DMO/FSA_C_RootTP.createChildFromRoot', 
    label: 'Create Child from Root (#ActionOverload)'
  }
]

Chart

Search term: #ChartSection

As an alternative to micro charts in the header, charts are also possible as sections. However the implementation is more complex. As aggregation is not yet available for V4 services, which this app is based on, the following shows only an example of how a chart should be annotated.

First the entity needs @Aggregation.default annotations, which defines which aggregation methods are supported. This can only be done on views that are not transactional.

Note

Source: CDS View /DMO/FSA_I_Chart

define view entity /DMO/FSA_I_Chart
  as select from zfsa_chart_a
  ...
{
  key id                             as ID,
      ...

      @EndUserText.label : 'Minimal Net Amount'
      @Aggregation.default: #MIN
      integer_value                  as MinAmount,

      @EndUserText.label : 'Maximal Net Amount'
      @Aggregation.default: #MAX
      integer_value                  as MaxAmount,

      @EndUserText.label : 'Average Net Amount'
      @Aggregation.default: #AVG
      integer_value                  as AvgAmount,
      ...
}

After that the @UI.chart can be defined. Please note, that the attribute measures contains the properties of the aggregation methods. If it is just a property of the entity, like "integerValue", the chart won't be displayed. The first property in the attribute dimensions has the default dimension. The second property is the category into which a drill down is possible.

The added actions to the attribute actions are shown in the chart toolbar.

Note

Source: CDS View /DMO/FSA_C_ChartTP

// Search Term #ChartSection
@UI.chart: [
  { 
    qualifier: 'Test',
    title: 'Chart (#ChartSection)',
    chartType: #COLUMN,
    dimensions: ['Dimensions', 'CriticalityCode'],
    measures: ['MaxAmount'],
    dimensionAttributes: [
      { 
        dimension: 'Dimensions', 
        role: #CATEGORY 
      },
      { 
        dimension: 'CriticalityCode', 
        role: #CATEGORY 
      }
    ],
    measureAttributes: [
      { 
        measure: 'MaxAmount',
        role: #AXIS_1
      }
    ],
    actions: [{ type: #FOR_ACTION, dataAction: 'updateChart', label: 'Action at Chart' }]
  }
]

Lastly the chart needs to be added to the @UI.facet annotation. :warning: This section is commented out in the Feature Showcase App as Aggregation annotations are still not yet available in V4 services

Note

Source: Metadata Extension /DMO/FSA_C_RootTP

// Search term #ChartSection
@UI.facet: [
  {
    id: 'chart',
    purpose: #STANDARD,
    type: #CHART_REFERENCE,
    targetElement: '_Chart',
    label: 'Chart (#ChartSection)'
  }
]

For semantic coloring of a dimension, the dimension property "CriticalityCode" is annotated with @UI.valueCriticality, where possible values of the property are matched against a criticality.

Note

Source: Metadata Extension /DMO/FSA_C_ChartTP

// Search Term #ChartSection
@UI.valueCriticality: [
  { 
    value: '1',
    criticality: #NEGATIVE
  },
  { 
    value: '2',
    criticality: #CRITICAL
  },
  { 
    value: '3',
    criticality: #POSITIVE
  }
]
CriticalityCode;
