EFSA SAS Stored Macros and Functions (MSTORE)

Macros

SAS macros are stored in the MSTORE library. If you need to use one of these functions, make sure to include in the code the following statement:

options mstored sasmstore=MSTORE;

This will tell SAS where to search for the stored macros.


stringTokenizer

%stringTokenizer(string, separator, token)

Parses a string which is composed of several tokens separated by the separator character. It executes the code below it for each retrieved token, which is saved inside the token variable. The statement must be closed with the %endStringTokenizer macro.

Parameters:

string - string which needs to be tokenized separator - character which separates the tokens inside the string token - output variable which is generated by the macro containing the current retrieved token

Dependencies:

Requires MSTORE.strings package to be loaded.

Examples:

data _null_;
  /* it is like a for loop iterated on the tokens */
  %stringTokenizer("first$second$third", "$", myToken)
    putlog "current token" myToken=;
  %endStringTokenizer
run;

iterateFacets

%iterateFacets(facets, facet, facetHeader, facetCode)

Works as the String Tokenizer macro, but it provides an improved interface to parse facets. In particular, it parses the facets variable and it executes the code below the iterateFacets statement for each facet, providing the current processed facet, its header and its code. The statement must be closed with the %endIterateFacets macro.

Parameters:

facets - facets list composed of facets with header and code, $-separated facet - the currently processed facet facetHeader - the header of the currently processed facet facetCode - the code of the currently processed facet

Dependencies:

Requires MSTORE.strings package to be loaded.

Examples:

This will print inside the log a line for each facet with the facet information:

data _null_;
  %iterateFacets("F01.BBB$F02.CCC", fac, head, code)
    putlog "facet (header+code)" fac "facet header" head "facet code" code;
  %endIterateFacets
run;

appendDataset

%macro appendDataset(data, out)

Appends data to the out table. If out does not exist, it will be created

Parameters:

data - dataset which will be appended to out out - name of the dataset in which data will be appended

Examples:

data AAA;
        A = 1;
        B = 2;
        output;
run;
%appendDataset(AAA, BBB); /* BBB will be created with one row as copy of AAA */
/* Now BBB exists */
%appendDataset(AAA, BBB); /* AAA will be appended to BBB (two rows now) */

deleteDataset

%macro deleteDataset(data)

Deletes the dataset data if it exists. If it does not, no action is performed.

Parameters:

data - dataset which will be deleted (put also the library name for non “work” datasets)

Examples:

%deleteDataset(NOT_EXISTING_DATA);  /* No action performed */

data AAA;
  a = 1;
run;

%deleteDataset(AAA); /* AAA will be deleted */

assertExists

%macro assertExists(dataset)

Asserts that the dataset passed as input exists, it gives an error in the SAS log otherwise. Function meant to be used only for creating test cases.

Parameters:

dataset - the SAS dataset which needs to be checked (put also the library name if needed)

Examples:

Example of false assertion:

%assertExists("AAA");  /* This will print an error in the log */

Example of true assertion:

data BBB;
run;

%assertExists("BBB");  /* OK, no error is printed */

assertNotExists

%macro assertNotExists(dataset)

Asserts that the dataset passed as input does not exist, it gives an error in the SAS log otherwise. Function meant to be used only for creating test cases.

Parameters:

dataset - the SAS dataset which needs to be checked (put also the library name if needed)

Examples:

Example of true assertion:

%assertNotExists("AAA");  /* OK, no error is printed */

Example of false assertion:

data BBB;
run;

%assertNotExists("BBB");  /* This will print an error in the log */

assertEqualsValue

%macro assertEqualsValue(expected, found)

Asserts that expected is equal to found, it gives an error in the SAS log otherwise. Function meant to be used only for creating test cases.

Parameters:

expected - the expected value for a variable found - the actual value found for a variable

Examples:

data AAA;
  a = 1;
  b = 1;
  output;
  a = 1;
  b = 2;
  output;
run;

/* if a = 1 then b should be 1 */
data _null_;
  set AAA;
  if (a = 1) then %assertEqualsValue(1, b);
run;

assertNobsEquals

%macro assertNobsEquals(dataset, expectedNum)

Asserts that the number of rows of the dataset is equal to the expectedNum, it gives an error in the SAS log otherwise. Function meant to be used only for creating test cases.

Parameters:

dataset - the SAS dataset which needs to be checked (put also the library name if needed) expectedNum - the expected number of observations which should be present in the dataset

Dependencies:

Requires MSTORE.tables package to be loaded.

Throws:

An error is thrown if dataset does not exist.

Examples:

Example of true assertion:

data AAA;
  a = 1;
  output;
run;

run;
%assertNobsEquals(AAA, 3);

DEAV_ENRICH_AND_VALIDATE

%macro DEAV_ENRICH_AND_VALIDATE(
inputTable=, 
outputTable=,
action=, 
parNames=,
parValues=,
dcfId=ID,
datasetId=DATASET_ID,
uniqueIdentifier=)

Interface for applying a general data enrichment and validation step inside the business rules engine. It enriches and validates the inputTable according to the required action. Each action has its own set of parameters which must be specified in the parNames and parValues parameters. In particular, parNames contains the names of the parameters and parValues their values (in the same order! See examples for further details).

Parameters:

inputTable - Input dataset which must be enriched/validated

outputTable - Table in which the data enrichment and validation errors are put. Note that this table will be created by the algorithm, therefore it should not exist before calling the macro.

action - The required data enrichment and validation action. Possible values are: - “FOODEX2_VALIDATION”, it validates a list of FoodEx2 codes and put the errors in the outputTable - “FOODEX2_TO_MATRIX”, it converts a list of FoodEx2 codes into matrix codes. A new column is added to the inputTable containing the matrix code (this column will be named as specified in the matrixColumn parameter)

parNames - Macro variable, list of comma separated names which identifies the specific parameters of a DEAV step. Note that since it is a comma separated list, it requires the %quote statement to be passed as input. Possible values are: - foodex2Column, used to specify a FoodEx2 column. For example, this can be used for the FoodEx2 validation or for the FoodEx2 to matrix mapping. - foodex2Hierarchy, used to specify the code of a FoodEx2 hierarchy. For example, this can be used to specify a hierarchy in which the FoodEx2 validation should be evaluated. - matrixColumn, used to specify a matrix code column. For example, this can be used for the FoodEx2 to matrix mapping.

parValues - Macro variable, list of comma separated values of the passed parameters listed in parNames. The order must be the same, that is, the first value in parValues is the value of the parameter named in the first value of parNames. Note that since it is a comma separated list, it requires the %quote statement to be passed as input.

dcfId - Name of the column of the input dataset containing the DCF id field. By default, it is ID.

datasetId - Name of the column of the input dataset containing the dataset id field. By default it is DATASET_ID.

uniqueIdentifier - Name of the column of the input dataset containing the record unique identifier field.

Dependencies: Add this piece of code before calling the macro:

options mstored sasmstore=MSTORE;
options fmtsearch=(FMTLIB BRS_STG); /* Required to use BR formats for parents */
options cmplib=(MSTORE.strings MSTORE.catalogues MSTORE.mtx MSTORE.dcf MSTORE.DEAV MSTORE.FOODEX2_VALIDATION MSTORE.tables);

Examples: It validates the “FX2” FoodEx2 column of the MY_DATA dataset. The validation results are returned in MY_ERRORS.

data MY_DATA;
  FX2 = "A0BA0"; output;
  FX2 = "A029F#F20.A07QQ$F21.A07RV"; output;
run;

%let parNames=foodex2Column;
%let parValues=FX2;

%DEAV_ENRICH_AND_VALIDATE(inputTable=MY_DATA, outputTable=MY_ERRORS, action="FOODEX2_VALIDATION", parNames=%quote(&parNames.), parValues=%quote(&parValues.));

It validates the “FX2” FoodEx2 column of the MY_DATA dataset using the reporting hierarchy as parent-child relationships evaluator. The validation results are returned in MY_ERRORS.

data MY_DATA;
  FX2 = "A0BA0"; output;
  FX2 = "A029F#F20.A07QQ$F21.A07RV"; output;
run;

%let parNames=foodex2Column,foodex2Hierarchy;
%let parValues=FX2,"REPORT";

%DEAV_ENRICH_AND_VALIDATE(inputTable=MY_DATA, outputTable=MY_ERRORS, action="FOODEX2_VALIDATION", parNames=%quote(&parNames.), parValues=%quote(&parValues.));

It maps the “FX2” FoodEx2 column of the MY_DATA dataset into matrix codes which will be inserted in a new column named “MATRIX”.

data MY_DATA;
  FX2 = "A0BA0"; output;
  FX2 = "A029F#F20.A07QQ$F21.A07RV"; output;
run;

%let parNames=foodex2Column,matrixColumn;
%let parValues=FX2,MATRIX;

%DEAV_ENRICH_AND_VALIDATE(inputTable=MY_DATA, outputTable=MY_ERRORS, action="FOODEX2_TO_MATRIX", parNames=%quote(&parNames.), parValues=%quote(&parValues.));

DEAV_FOODEX2_VALIDATION

%macro DEAV_FOODEX2_VALIDATION(inputTable=, outputTable=, idColumns=, foodex2Column=, foodex2Hierarchy=, checkReportability=0, checkDeprecated=0, statistics=0)

Validates a set of FoodEx2 codes and returns the errors/warnings.

Parameters:

inputTable - Input table containing the data to validate

outputTable - Output table which will contain the detected errors. This table will be created by the algorithm.

idColumns - List of space separated columns names which specify the fields which identify a row of the inputTable. foodex2Column - The name of the column of input containing the FoodEx2 code to validate

foodex2Hierarchy - Optional parameter, it specifies which hierarchy should be used for performing additional validation steps, as the FOODEX.19 business rule. If omitted, the additional checks are skipped.

checkReportability - Optional parameter, it specifies if the algorithm should check the term reportability, that is, if a not reportable term/facet is used then an error is raised (0/1 values). Note that this will evaluate the up-to-date reportability of terms, without taking into consideration the period of time in which the terms were reported. This makes these checks not applicable to historical data, where the reportability of terms could be different. By default, terms reportability is not checked (i.e. 0 value).

checkDeprecated - Optional parameter, it specifies if the algorithm should highlight the use of deprecated terms/facets as an error (0/1 values). Note that this will evaluate the up-to-date deprecated state of terms, without taking into consideration the period of time in which the terms were reported. This makes these checks not applicable to historical data, where deprecated terms could be different. By default, deprecated terms are not checked (i.e. 0 value).

statistics - Optional parameter, it specifies if the algorithm performances should be evaluated or not while running the algorithm (0/1 values). By default, no statistics is computed (i.e. 0 value).

Missing implementation The procedure does not check if a term exist, it should be added. This leads also to a not always consistent deprecated check. For example, consider the case of A002M#F01.A002M. The code A002M does not exist in the F01 hierarchy, but an error will still be raised since the term itself is deprecated in general.

Dependencies: Add this piece of code before calling the macro:

options mstored sasmstore=MSTORE;
options fmtsearch=(FMTLIB BRS_STG); /* Required to use BR formats for parents */
options cmplib=(MSTORE.strings MSTORE.catalogues MSTORE.mtx MSTORE.dcf MSTORE.DEAV MSTORE.FOODEX2_VALIDATION MSTORE.tables);

Examples:

data MY_DATA;
  DCFID = 1;
  DATASET_ID = 2;
  FOODEX = "A029F#F20.A07QQ$F21.A07RV";
run;
%DEAV_FOODEX2_VALIDATION(inputTable=MY_DATA, outputTable=ERR_TABLE, idColumns=DCFID DATASET_ID, foodex2Column=FOODEX); /* without hierarchy */

%DEAV_FOODEX2_VALIDATION(inputTable=MY_DATA, outputTable=ERR_TABLE, idColumns=DCFID DATASET_ID, foodex2Column=FOODEX, foodex2Hierarchy="REPORT"); /* with reporting hierarchy */

%DEAV_FOODEX2_VALIDATION(inputTable=MY_DATA, outputTable=ERR_TABLE, idColumns=DCFID DATASET_ID, foodex2Column=FOODEX, statistics=1); /* compute statistics without hierarchy */

%DEAV_FOODEX2_VALIDATION(inputTable=MY_DATA, outputTable=ERR_TABLE, idColumns=DCFID DATASET_ID, foodex2Column=FOODEX, foodex2Hierarchy="REPORT", statistics=1); /* compute statistics with reporting hierarchy */

DEAV_FOODEX2_TO_MATRIX (NOT IMPLEMENTED YET)

%macro DEAV_FOODEX2_TO_MATRIX(inputTable=, outputTable=, idColumns=, foodex2Column=, 
matrixColumn=, statistics=0)

Maps a FoodEx2 column to matrix code.

Parameters:

inputTable - Input table containing the FoodEx2 codes outputTable - Output table which will contain the process errors (if any) idColumns - List of space separated columns names which specify the fields which identify a row of the inputTable. foodex2Column - The name of the column of input containing the FoodEx2 code to map matrixColumn - The name of the column which will be created in the input table containing the mapped matrix code statistics - Optional parameter, it specifies if the algorithm performances should be evaluated or not while running the algorithm (0/1 values). By default, no statistics is computed (i.e. 0 value).

Examples:

data MY_DATA;
  ID = 1;
  FOODEX = "A029F#F20.A07QQ$F21.A07RV";
run;

%DEAV_FOODEX2_TO_MATRIX(inputTable=MY_DATA, outputTable=ERR_TABLE, idColumns=ID, foodex2Column=FOODEX, matrixColumn=MATRIX); /* No statistics computed */

%DEAV_FOODEX2_TO_MATRIX(inputTable=MY_DATA, outputTable=ERR_TABLE, idColumns=ID, foodex2Column=FOODEX, matrixColumn=MATRIX, statistics=1); /* with performance statistics */

DEAV_CREATE_EMPTY_ERR_TABLE

%macro DEAV_CREATE_EMPTY_ERR_TABLE(errorTable)

Creates an empty data enrichment and validation error table. The error table structure is the following:

ROW_ID ERR_CODE ERR_TYPE ERR_MESSAGE ERR_COLUMN ERR_VALUE
integer code of the error type of error error message involved column involved column value

A single error can create multiple rows (with same ROW_ID, ERR_CODE, ERR_TYPE, ERR_MESSAGE but different ERR_COLUMN with its own ERR_VALUE). This is used to have a table which can accommodate a dynamic set of erroneous columns.

Parameters:

errorTable - name of the table which will be created


Functions

SAS functions are stored in the MSTORE library and organized in several packages. If you need to use a function of a specific package, you will have to write a command to import that package in your code. For example, if it is required to use a function inside the MSTORE.strings package, it is needed to provide the following code:

options cmplib=(MSTORE.strings);

If two or more packages are needed, specify them space-separated in the same option, such as:

options cmplib=(MSTORE.strings MSTORE.catalogues);

This will enable using the functions of both strings and catalogues packages. In the following Sections every package and its functions are described.


1 - MSTORE.catalogues

This package contains handy functions for managing catalogues data and metadata.


getHierarchyByAttributeCode

function getHierarchyByAttributeCode(catalogueCode $, attrCode $) $ 400

Returns the code of an hierarchy of type “attribute” starting from the attribute code related to the hierarchy.

Parameters:

catalogueCode - The code of the catalogue containing the attribute and the hierarchy to retrieve attrCode - The code of the attribute which is related to the hierarchy to retrieve

Returns:

The code of the hierarchy related to the attribute if found, otherwise an empty string. If the attrCode or the catalogueCode do not exist in the CATALOG library, then 0 is returned.

Dependencies:

Requires stored macro to be correctly executed. See Macros for further details.

Examples:

Regarding the MTX catalogue, if the value “F01” is given as attrCode, the function will return “source”, because the source hierarchy is related to the F01 attribute.

data _null_;
  hierarchy = getHierarchyByAttributeCode("MTX", "F01");
  putlog hierarchy=;  /* This will return "source" */
run;

getAncestorAtLevel

function getAncestorAtLevel(term $, hierarchy $, level $) $ 4000

Returns the code of a term which is ancestor of the term specified in the input parameters at a certain level of the considered hierarchy.

Parameters:

term - Code of the term from which the retrieval of the ancestor is started hierarchy - Code of the hierarchy in which the ancestor of the term are searched level - Absolute level of the required ancestor in the selected hierarchy tree. In particular, level = 1 targets root ancestors, level = 2 targets ancestors in the second level of the hierarchy and so on. If the direct parent is needed, it is necessary to know the level of the child term and use that number minus 1.

Returns:

The code of the ancestor at the selected level in the hierarchy if found, otherwise empty string. If the level parameter is equal to the level of the child term, then the child term code is returned as if it was the ancestor of itself. If term does not exist in the hierarchy an empty string is returned. If level is bigger than zero and also bigger than the hierarchy level in which lies the child term, then an empty string is returned.

Dependencies:

Requires Business Rules format, add the following to your code:

options fmtsearch=(FMTLIB BRS_STG);

Throws:

An error is thrown if a level value less than 1 is passed. An error is thrown if a non-existing hierarchy code is passed.

Examples:

Get root ancestor of Barley grain, pearled in the reporting hierarchy :

data _null_;
  ancestor = getAncestorAtLevel("A002K", "REPORT", 1);
  putlog ancestor=;  /* Root ancestor is "A0B6Z" which is "Food" */
run;

Get direct parent of Barley grain, pearled in the reporting hierarchy :

data _null_;
  /* Get parent of "Barley grain, pearled" in reporting hierarchy */
  /* Since "Barley grain, pearled" is at the 7-th level in the reporting hierarchy, the 6-th level is used to target the direct parent */
  parent = getAncestorAtLevel("A002K", "REPORT", 6);
  putlog parent =;  /* parent is "A000P" which is "Barley grains" */
run;

Print all the parents of Barley grain, pearled in the reporting hierarchy:

data _null_;
  i = 1;
  do until (i = 8);
    parent = getAncestorAtLevel("A002K", "REPORT", i);
    putlog i= parent =;
    i = i + 1;
  end;
run;

getAncestors

function getAncestors(term $, hierarchy $) $ 4000

Returns:

String of ancestors codes dash-separated. if the term code does not exist in the hierarchy, an empty string is returned.

Dependencies:

Requires Business Rules format, add the following to your code: options fmtsearch=(FMTLIB BRS_STG);

Throws:

An error is thrown if a non-existing hierarchy code is passed.

Examples:

Get ancestors of Barley grain, pearled in the reporting hierarchy:

Returns:

Returns 1 if the term is a descendant of the target term in the considered hierarchy, otherwise 0. If a non existing term or non existing target is passed, then 0 is returned.

Dependencies:

Requires Business Rules format, add the following to your code: options fmtsearch=(FMTLIB BRS_STG);

Throws:

An error is thrown if a non-existing hierarchy code is passed.

Examples:

Check if "Cereal grains (and cereal-like grains)" is ancestor of "Barley grain, pearled”:

data _null_;
  if isAncestor("A002K", "A000L", "REPORT") then putlog "Yes, it is an ancestor";
  else putlog "Not, it is not an ancestor";

Returns:

A distinct facets list extracted from the facets string, $-separated.

Dependencies:

Requires stored macro to be correctly executed. See Macros for further details.

function countFacets(facets $, facetHeader $)

Counts the number of facets in the facets string which have as header the specified facetHeader.

Parameters:

facets - string containing a list of facets $-separated with both header and code facetHeader - the target header the facets must have to be counted by the function

Returns:

The number of facets inside the facets string with the target facetHeader.

Dependencies:

Requires stored macro to be correctly executed. See Macros for further details.

Examples:

countFacetsNotChildOfImplicit

function countFacetsNotChildOfImplicit(facets $, implicitFacets $, facetHeader $)

Counts the number of facets inside the facets string with header facetHeader which are not descendant of the facets contained in the implicitFacets string. This is helpful for validation purposes, where it is needed to check if the explicit facets are actually descendant of the implicit facet, or not. Note that the term relationships are evaluated in the facet hierarchies identified by the header of the facet (e.g. facets with header F01 are checked in the source hierarchy of the MTX). Note also that in case of multiple implicit facets for the same facet category, the term should not be a descendant of all the implicit facets, in order to be counted.

Parameters:

facets - string containing a list of facets $-separated with both header and code facetHeader - the target header the facets must have to be counted by the function implicitFacets - list of implicit facets $-separated with both header and code

Returns:

The number of facets inside the facets string with the target facetHeader which are not descendant of the implicit facets.

Dependencies:

Requires MSTORE.catalogues package to be loaded. Requires stored macro to be correctly executed. See Macros for further details.

Examples:

F27.A026V Fish (meat) is not a child of the implicit F27.A02BT Cods, hakes, haddocks, therefore it will be counted.

data _null_;
  /* F27.A026V Fish (meat) is not a child of the implicit F27.A02BT */
  count = countFacetsNotChildOfImplicit("F27.A026V",
    "F02.A0EMT$F27.A02BT$F28.A07KG", "F27");

getExplicitNotChildOfImplicit

function getExplicitNotChildOfImplicit(facets $, implicitFacets $, facetHeader $)$4000

Extracts the facets inside the explicits string with header facetHeader which are not descendant of the facets contained in the implicits string. Note that the term relationships are evaluated in the facet hierarchies identified by the header of the facet (e.g. facets with header F01 are checked in the source hierarchy of the MTX). Note also that in case of multiple implicit facets for the same facet category, the term should not be a descendant of all the implicit facets, in order to be put in output.

Parameters:

facets - string containing a list of facets $-separated with both header and code implicitFacets - the target header the facets must have to be counted by the function facetHeader - list of implicit facets $-separated with both header and code

Returns:

The facets inside the facets string with the target facetHeader which are not descendant of the implicit facets, $-separated.

Dependencies:

Requires MSTORE.catalogues package to be loaded. Requires stored macro to be correctly executed. See Macros for further details.

Examples:

F27.A026V Fish (meat) is not a child of the implicit F27.A02BT Cods, hakes, haddocks, therefore it will be put in output.

data _null_;
  /* F27.A026V Fish (meat) is not a child of the implicit F27.A02BT */
  count = getExplicitNotChildOfImplicit("F27.A026V",
    "F02.A0EMT$F27.A02BT$F28.A07KG", "F27");
  putlog count=; /* F27.A026V */
run;

checkFacetCardinality

function checkFacetCardinality(facets $, facetHeader $)

Checks if the cardinality of the facets with header facetHeader is respected or not.

Parameters:

facets - string containing a list of facets $-separated with both header and code facetHeader - the target header the facets must have to be counted by the function

Returns:

1 if the cardinality of the facet identified by the facetHeader is respected, 0 otherwise.

Dependencies:

Requires MSTORE.catalogues package to be loaded Requires stored macro to be correctly executed. See Macros for further details.

Examples:

Source commodity is repeatable and therefore it is possible to specify more than one F27:

data _null_;
      if checkFacetCardinality("AhHSS#F01.A000A$F27.B00SB$F27.BSJHR", "F27")
        then putlog "Respected";
      else putlog "Not respected"; /* Respected */
run;

Source is not repeatable and therefore it is not possible to specify more than one F01:

data _null_;
      if checkFacetCardinality("AhHSS#F01.A000A$F01.B00SB$F27.BSJHR", "F01")
        then putlog "Respected";
      else putlog "Not respected"; /* Not respected */
run;

getFacetsByCategory

function getFacetsByCategory(facets $, facetHeader $) $ 4000

Extracts from the facets string the facet which have the selected facet category (i.e. header).

Parameters:

facets - string containing a list of facets $-separated with both header and code facetHeader - the target header the facets must have to be counted by the function

Returns:

A string a list of facets $-separated with both header and code which have as header the passed facetHeader

Dependencies:

Requires stored macro to be correctly executed. See Macros for further details.

Examples:

Get only the F27 facets:

data _null_;
  f = getFacetsByCategory("F02.A0EMT$F27.A920K$F27.A02BT$F28.A07KG", "F27");
  putlog f=; /* F27.A920K$F27.A02BT */
run;

removeRedundantExplicitFacets

function removeRedundantExplicitFacets(explicits $, implicits $) $ 4000

Removes the not repeatable explicit facets which are ancestors of the implicit facets. This is because they are redundant and less detailed than the implicit ones. Note that the ancestor-descendant relationship is based on the facet hierarchies, depending on the facet header.

Parameters:

explicits - string containing a list of explicit facets $-separated with both header and code implicits- string containing a list of implicit facets $-separated with both header and code

Returns:

A string containing the explicit facets $-separated with both header and code which are not ancestors of the implicit facets.

Dependencies:

Requires MSTORE.catalogues and MSTORE.strings packages to be loaded Requires stored macro to be correctly executed. See Macros for further details.

Examples:

The explicit facet F01.A059A Amaranth (as plant) is ancestor of the implicit F01.A0E0E Chinese amaranth (as plant) in the SOURCE hierarchy and therefore it will be removed. Note that this happens only because the F01 facet is not repeatable!

data _null_;
  f = removeRedundantExplicitFacets("F02.A0EMT$F01.A059A", "F01.A0E0E");
  putlog f=; /* F02.A0EMT */
run;

addImplicitFacets

function addImplicitFacets(explicits $, implicits $) $ 4000

Parameters:

explicits - string containing a list of explicit facets $-separated with both header and code implicits- string containing a list of implicit facets $-separated with both header and code

Returns:

A string of merged facets $-separated with both header and code.

Dependencies:

Requires MSTORE.catalogues and MSTORE.strings packages to be loaded Requires stored macro to be correctly executed. See Macros for further details.

Examples:

The explicit facet F01.A0E0E Chinese amaranth (as plant) is ancestor of the implicit A059A Amaranth (as plant) in the SOURCE hierarchy and therefore it will not be included in the output:

data _null_;
  merged = addImplicitFacets("F01.A0E0E", "F01.A059A$F27.A026V");
  putlog merged=; /* F01.A0E0E$F27.A026V */
