• What is the cause and solution for SAP error message DDLS434 - Deleted/changed association & still used in CDS view & ?

  The SAP error message DDLS434 indicates that there is a deleted or changed association in a Core Data Services (CDS) view that is still being referenced or used in another CDS view or object. This typically occurs when you modify the structure of a CDS view, such as removing or altering an association, but other views or objects still depend on the original structure.
  Cause:
  
  Deleted Association: An association that was previously defined in a CDS view has been deleted.
  Changed Association: An association has been modified (e.g., changed its name or type) but is still referenced in other CDS views or objects.
  Dependency: Other CDS views, reports, or applications are still trying to access the deleted or modified association.
  
  Solution:
  
  
  Identify Dependencies: Use the SAP tools to identify which CDS views or objects are still referencing the deleted or changed association. You can use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check for dependencies.
  
  
  Update Dependent Objects: Once you identify the dependent objects, you need to update them to remove or modify the references to the deleted or changed association. This may involve:
  
  Modifying the dependent CDS views to remove the references.
  Updating the logic in the dependent views to accommodate the changes.
  If necessary, re-creating the association in the original CDS view if it is still needed.
  
  
  
  Re-activate CDS Views: After making the necessary changes, re-activate the affected CDS views and any dependent objects to ensure that they are in sync with the current definitions.
  
  
  Check for Errors: After re-activating, check for any remaining errors or warnings in the system to ensure that all dependencies are resolved.
