• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG062 - Composition of CDS-View &1 contains duplicate views ?

  The SAP error message SADL_GEN_DRFT_MSG062 indicates that there is a problem with the composition of a Core Data Services (CDS) view in your SAP system. Specifically, it states that the CDS view contains duplicate views, which can lead to ambiguity and issues when trying to execute or utilize the view.
  Cause:
  The error typically arises from one of the following scenarios:
  
  Duplicate View Definitions: You may have defined multiple views with the same name or alias in the CDS view composition.
  Inclusion of the Same View Multiple Times: The same CDS view might be included multiple times in the composition, either directly or indirectly through other views.
  Incorrect Associations: If the associations between views are not properly defined, it can lead to duplication in the context of the view composition.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check View Definitions:
  
  Review the CDS view definition to ensure that there are no duplicate views being referenced. Look for any views that might have the same name or alias.
  
  
  
  Review Composition Logic:
  
  Examine the logic used to compose the CDS view. Ensure that each view is included only once and that there are no circular references or unintended duplications.
  
  
  
  Refactor Views:
  
  If you find that the same view is being included multiple times, refactor your CDS view to eliminate the duplicates. You may need to create a new view or modify existing ones to ensure that each view is only referenced once.
  
  
  
  Check for Dependencies:
  
  Investigate any dependent views that might be causing the duplication. If a view is included in another view that is also part of the composition, it could lead to duplication.
  
  
  
  Use Aliases:
  
  If you need to include the same view for different purposes, consider using aliases to differentiate between the instances.
  
  
  
  Activate Changes:
  
  After making the necessary changes, activate the CDS view and check if the error persists.
