3276230 - Custom field not visible/editable in Fiori app after upgrade to S/4HANA 2021

A custom field was visible/editable in a S/4HANA release prior to 2021. After upgrading to S/4HANA 2021 the custom field is no longer present or cannot be edited.

This happens when:

• The Fiori app´s UI is built using an RDS-based OData entity.
• The custom field is enabled for the CDS view of the affected OData entity
• The custom field is not enabled for the affected OData entity

This is the case, among others, for Fiori app “Purchase Requisition Professional” :

• Fiori application “Purchase Requisition Professional” uses the OData service MM_PUR_PR_PROFNL_MAINTAIN_SRV
• CDS view “Purchase Reqn Consumption Item View” C_PurchaseReqnItem is enabled in Custom Fields Fiori app
• OData service “Maintain Purchase Requisition Extensibility Model” MM_PUR_PR_PROFNL_MAINTAIN_SRV is not enabled in Custom Fields Fiori app
