  Cause:
  The error message SGSUB001 occurs due to the following reasons:
  
  Duplicate Implementation: You are trying to create a new implementation of a BAdI that already has an existing implementation defined.

  Modify Existing Implementation:
  
  If you need to make changes, you can modify the existing implementation instead of creating a new one.
  
  
  
  Delete or Deactivate Conflicting Implementation:
  
  If the existing implementation is not needed, you can delete or deactivate it. Be cautious with this approach, as it may affect other functionalities.
  
  
  
  Check for Namespace Conflicts:
  
  If you are working in a custom namespace, ensure that there are no conflicts with standard implementations or other custom implementations.
  
  
  
  Consult Documentation:
