• What is the cause and solution for SAP error message CHK_ENH802 - Composite implementation &1 is already a higher-level implementation ?

  The SAP error message CHK_ENH802 indicates that you are trying to create or modify a composite implementation in a way that conflicts with existing higher-level implementations. This typically occurs in the context of Business Add-Ins (BAdIs) or enhancement spots in SAP, where you are attempting to implement a composite BAdI that is already defined at a higher level.
  Cause:
  
  Existing Higher-Level Implementation: The composite implementation you are trying to create or modify already exists at a higher level, which means that the system does not allow you to create a new implementation that would override or conflict with it.
  Incorrect Hierarchy: You may be trying to implement a BAdI in a way that does not respect the hierarchy of implementations. For example, if a BAdI has a higher-level implementation, you cannot create a lower-level implementation that would conflict with it.
  
  Solution:
  
  Check Existing Implementations: Review the existing implementations of the BAdI to see if there is already a higher-level implementation. You can do this by navigating to the BAdI definition in transaction SE18 or SE19.
  Modify Existing Implementation: If you need to make changes, consider modifying the existing higher-level implementation instead of creating a new one.
  Use a Different Implementation: If your requirement is different from the existing implementation, you may need to create a new implementation that does not conflict with the existing ones. Ensure that you are not trying to create a composite implementation when a higher-level implementation already exists.
  Consult Documentation: Review the SAP documentation for the specific BAdI you are working with to understand its implementation hierarchy and any restrictions that may apply.
