• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK149 - Same Suffix &1 is used as Union Suffix in CDS registry &2 ?

  The SAP error message CFD_REGISTRY_CHECK149 indicates that there is a conflict in the suffixes used in the Core Data Services (CDS) registry. Specifically, it means that the same suffix is being used for both a regular entity and a union entity in the CDS registry, which is not allowed.
  Cause:
  The error occurs when:
  
  You have defined a CDS view or entity with a specific suffix (e.g., _SUFFIX) and then attempted to define another entity (or union) with the same suffix in the same context or namespace.
  This can happen if you are trying to create a union of multiple CDS views and inadvertently use the same suffix for both the union and one of the views.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Conflicting Suffixes:
  
  Check the CDS views or entities that are registered in the CDS registry. Look for the suffix mentioned in the error message (&1) and the registry (&2).
  
  
  
  Rename the Suffix:
  
  Change the suffix of either the conflicting entity or the union to ensure that they are unique. For example, if you have a view with the suffix _A and a union also trying to use _A, rename one of them to something else (e.g., _B).
  
  
  
  Adjust the CDS Definitions:
  
  After renaming, make sure to adjust any references to the renamed suffix in your CDS definitions or any dependent objects.
  
  
  
  Activate the Changes:
  
  Once you have made the necessary changes, activate the CDS views or entities again to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  After activation, test the CDS views or the union to ensure that they work as expected without any errors.
