• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK381 - CDS Value Help View and Leading View must not be identical ?

  The SAP error message "CFD_REGISTRY_CHECK381: CDS Value Help View and Leading View must not be identical" typically occurs in the context of Core Data Services (CDS) views in SAP. This error indicates that there is a configuration issue where a CDS value help view is incorrectly set to be identical to its leading view, which is not allowed.
  Cause:
  
  Identical Views: The error arises when the definition of a CDS value help view is the same as that of its leading view. In SAP, a value help view is meant to provide a list of possible values for a field, while the leading view is the primary data source for the CDS view. They should serve different purposes and thus should not be identical.
  Misconfiguration: This can happen due to a misconfiguration in the CDS view definitions, where the developer may have mistakenly set the value help view to point to the same data source as the leading view.
  
  Solution:
  To resolve this error, you need to ensure that the CDS value help view and the leading view are not identical. Here are the steps to do that:
  
  
  Review the CDS View Definitions:
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant development environment.
  Check the definition of both the value help view and the leading view.
  
  
  
  Modify the Value Help View:
  
  If the value help view is indeed identical to the leading view, modify it to ensure it retrieves a different set of data or includes additional fields that differentiate it from the leading view.
  You can create a new CDS view that serves as the value help view, ensuring it pulls from the same underlying data but presents it differently.
  
  
  
  Test the Changes:
  
  After making the necessary changes, activate the CDS views and test them to ensure that the error is resolved and that the value help functionality works as expected.
  
  
  
  Documentation and Comments:
  
  It’s a good practice to document the purpose of each view and add comments in the code to clarify the differences between the leading view and the value help view for future reference.
