• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG065 - Assoc. #TO_COMPOSITION_PARENT in CDS-View &1 is defined multiple times ?

  The SAP error message SADL_GEN_DRFT_MSG065 indicates that there is a problem with the definition of a CDS (Core Data Services) view, specifically related to the association TO_COMPOSITION_PARENT. This error occurs when the association is defined multiple times within the same CDS view, which is not allowed.
  Cause:
  The error is caused by one of the following scenarios:
  
  Duplicate Association Definition: The association TO_COMPOSITION_PARENT is defined more than once in the CDS view.
  Inheritance Issues: If the CDS view is inheriting from another view that also defines the same association, it can lead to conflicts.
  Incorrect Annotations: There may be incorrect or conflicting annotations that lead to the same association being interpreted multiple times.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the CDS View Definition:
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant editor.
  Look for the association TO_COMPOSITION_PARENT and ensure it is defined only once.
  
  
  
  Remove Duplicate Definitions:
  
  If you find multiple definitions of the same association, remove the duplicates. Ensure that only one definition remains.
  
  
  
  Review Inheritance:
  
  If your CDS view is inheriting from another view, check the parent view for the same association. If it exists there, you may need to adjust your view to avoid redefining it.
  
  
  
  Check Annotations:
  
  Review any annotations related to the association. Ensure that they are not causing the association to be interpreted multiple times.
  
  
  
  Test the Changes:
