[x] No

Other Information

Pending issues:

• display approval myAccount navigation item for cost center manager only if there are cost centers
• display remaining budget in the buyer approval widget instead of already spent including this order (or fix the value after customer approval has been done)
• remove "Please Select" of cost center in checkout if a cost center was already assigned to the basket
• customer approval is shown as required although the order spent limit is not exceeded - it has to be fixed within the ICM https://dev.azure.com/intershop-com/Products/_workitems/edit/70546/

Thank you for calling to talk about cost center approval. As discussed I found some issues during my review:

• Some blanks before colons, e.g. Approver : Patricia Miller.
• Cost center name is missing on some pages (only cost center no. or ID is visible).
• Approval status per approver should be displayed (maybe a success check icon when approver approved it) for pending requisitions. This allows the buyer to see which approver still needs to check the requisition.
• Info message "The requisition still needs approval..." has missing styles (maybe Purge CSS thing).
• If requisition was approved by me but is pending due to a missing second approval, the requisition should be listed in the "Approved by me" section regardless of the overall approval status. Currently requisition is no longer visible to me until second approval is done. Tabs have been renamed to "Approved Requisitions" and "Rejected Requisitions"
• If approver approves/rejects the requisition, go automatically back to "Waiting for your approval" list because there is nothing left to do for the requisition.
• Cost center approval widget is no longer visible for cost center manager after the requisition is approved or rejected.
• All approvers should be listed for an approved requisition (currently the last approver is displayed).

Please look at the points that you can fix. Leave the other points open for discussion for the REST interface.
