SADL_GW_DT_CDS024 - Details

• The SAP error message SADL_GW_DT_CDS024 indicates that there is an issue with the definition of a CDS (Core Data Services) view where an association named TO_COMPOSITION_PARENT is defined multiple times. This typically occurs when the same association is declared more than once within the same CDS view or when there are conflicting definitions in the associated views.
  
  Cause:
  
  Duplicate Association Definition: The most common cause is that the association TO_COMPOSITION_PARENT is defined multiple times in the same CDS view or in the views that are being used in the CDS view.
  Inconsistent Associations: If the association is defined in multiple places with different characteristics (e.g., different cardinalities or filters), it can lead to this error.
  Inheritance Issues: If the CDS view is inheriting from another view that also defines the same association, it can cause a conflict.
  
  
  Solution:
  
  Check for Duplicates: Review the CDS view definition to ensure that the association TO_COMPOSITION_PARENT is defined only once.
