• What is the cause and solution for SAP error message SPRX373 - Fault messages of operation &1 are not unique ?

  The SAP error message SPRX373 indicates that there are multiple fault messages associated with a specific operation, and they are not unique. This typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when dealing with service interfaces and message mappings.
  Cause:
  
  
  Duplicate Fault Messages: The error arises when the system encounters multiple fault messages that are defined for the same operation. This can happen if:
  
  The same fault message is defined multiple times in the interface mapping.
  There are multiple service interfaces that define the same fault message for the same operation.
  
  
  
  Configuration Issues: Incorrect configuration in the Enterprise Services Repository (ESR) or Integration Directory can lead to this error.
  
  
  Versioning Conflicts: If there are different versions of the same service interface or operation, it may lead to ambiguity in fault message resolution.
  
  
  Solution:
  
  
  Check Fault Message Definitions:
  
  Go to the Enterprise Services Repository (ESR) and check the definitions of the fault messages associated with the operation in question.
  Ensure that each operation has a unique fault message defined.
  
  
  
  Remove Duplicates:
  
  If you find duplicate fault messages, remove or consolidate them to ensure that each operation has a single, unique fault message.
  
  
  
  Review Interface Mappings:
  
  Check the interface mappings in the Integration Directory to ensure that they are correctly configured and do not reference multiple fault messages for the same operation.
  
  
  
  Version Management:
  
  If you are using different versions of service interfaces, ensure that the correct version is being used and that it does not conflict with other versions.
  
  
  
  Testing:
  
  After making changes, test the integration scenario to ensure that the error is resolved and that the fault messages are being handled correctly.
