• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG108 - Key Fields for CDS view &1 and draft view &2 not generated (Union) ?

  The SAP error message SADL_GEN_DRFT_MSG108 indicates that there is an issue with the generation of key fields for a Core Data Services (CDS) view and its associated draft view. This error typically arises when there is a problem with the definition of the CDS view, particularly in the context of union operations.
  
  Cause:
  
  Missing Key Fields: The CDS view or the draft view may not have the necessary key fields defined. For a draft-enabled CDS view, key fields are essential for identifying records uniquely.
