  The SAP error message SRT_WSP2012 indicates that there is no target operation found in the Mediation Layer for the specified mapping and message. This error typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when dealing with web service calls.
  Cause:
  
  Missing Target Operation: The most common cause is that the target operation defined in the web service call does not exist in the Mediation Layer. This could be due to incorrect configuration or a mismatch between the service definition and the actual implementation.
  Incorrect Mapping: The mapping specified in the error message may not be correctly defined or may not correspond to any existing operation in the Mediation Layer.
  Service Definition Issues: The service definition in the Enterprise Services Repository (ESR) may not be properly aligned with the actual implementation in the Integration Directory.

  Test with SOAP UI: Use a tool like SOAP UI to test the web service call directly. This can help identify if the issue is with the service itself or with the configuration in SAP PI/PO.
  Check Logs: Review the logs in the SAP PI/PO system for any additional error messages or warnings that may provide more context about the issue.
  Re-deploy or Activate Objects: If changes were made to the service definitions or mappings, ensure that all relevant objects are activated and re-deployed as necessary.
