  Cause:
  This error typically occurs when:
  
  Duplicate Mappings: There are multiple mappings defined for the same interface and sender combination. This can happen if mappings were created incorrectly or if there are overlapping configurations.

  Check Existing Mappings:
  
  Go to the relevant transaction in SAP (such as the Integration Builder or the relevant mapping configuration area).

  Identify if there are multiple mappings for the same combination.
  
  
  
  Remove or Modify Duplicates:
  
  If you find duplicate mappings, decide which one is correct and remove or deactivate the others.
  Ensure that the remaining mapping is correctly configured to handle the messages as intended.
  
  
  
  Review Mapping Logic:
  
  Check the logic of the mapping to ensure it is correctly set up to handle the incoming messages.
  Validate that the mapping is not only unique but also correctly aligned with the business requirements.
  
  
  
  Test the Configuration:

  Use test messages to verify that the mapping works as expected.
