• What is the cause and solution for SAP error message SADL_GW_DT_CDS003 - Association &1 is exposed multiple times. ?

  The SAP error message SADL_GW_DT_CDS003 indicates that an association in a Core Data Services (CDS) view is exposed multiple times. This typically occurs when there are multiple associations defined in a CDS view that point to the same target entity or when the same association is included in multiple places within the same view or in related views.
  Cause:
  
  Duplicate Associations: The same association is defined more than once in the CDS view.
  Multiple Inclusions: The association might be included in multiple places, such as in different projections or joins within the same CDS view.
  Inheritance: If the CDS view inherits from another view that already has the same association, it can lead to duplication.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the CDS View Definition:
  
  Check the definition of the CDS view for any duplicate associations. Ensure that each association is defined only once.
  
  
  
  Remove Duplicates:
  
  If you find that an association is defined multiple times, remove the duplicates. Keep only one definition of the association.
  
  
  
  Check Inherited Views:
  
  If your CDS view inherits from another view, check the parent view for the same association. If it exists there, you may not need to redefine it in the child view.
  
  
  
  Use Aliases:
  
  If you need to reference the same association multiple times for different purposes, consider using aliases to differentiate them.
  
  
  
  Test the Changes:
  
  After making the necessary changes, activate the CDS view and test it to ensure that the error is resolved.
