• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG404 - CDS-View &1 cannot be draft-enabled because of underlying BO-View. ?

  The SAP error message SADL_GEN_DRFT_MSG404 indicates that a Core Data Services (CDS) view cannot be draft-enabled due to issues with the underlying Business Object (BO) view. This error typically arises when there are certain constraints or configurations in the underlying data model that prevent the draft functionality from being applied.

  @ObjectModel.draftEnabled: true
  
  Simplify Relationships: If the BO view has complex relationships, consider simplifying them or restructuring the view to make it compatible with draft scenarios.
  Check Data Types: Review the data types used in the BO view and ensure they are compatible with draft handling.
