  The SAP error message SRT_WSP3138 indicates that the incoming port for a web service is not properly configured or is missing. This error typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when dealing with web service communication.
  Cause:
  The error is triggered when the system expects a valid incoming port configuration for a web service but finds that it is either not set or is empty (initial). This can happen due to several reasons:
  
  The web service configuration is incomplete or incorrect.
  The service endpoint is not properly defined in the service registry.
  There may be issues with the service definition in the Enterprise Services Repository (ESR).
  The communication channel for the web service is not activated or is misconfigured.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Service Configuration:
  
  Go to the SAP PI/PO system and check the configuration of the web service.
  Ensure that the incoming port is correctly defined in the service definition.

  Test the Web Service:
  
  Use tools like SOAP UI or Postman to test the web service endpoint directly. This can help identify if the issue is with the service itself or the configuration in SAP.
  
  
  
  Consult Logs:
