• What is the cause and solution for SAP error message SRT_WSP170 - No configuration for proxy class "&1" and logical port "&2" ?

  The SAP error message SRT_WSP170 indicates that there is no configuration for the specified proxy class and logical port in the SAP system. This error typically occurs when you are trying to call a web service, but the necessary configuration for the web service proxy is missing or incorrect.
  Cause
  The error can be caused by several factors:
  
  Missing Configuration: The logical port or proxy class has not been configured in the SAP system.
  Incorrect Logical Port: The logical port specified in the call does not exist or is not correctly defined.
  Proxy Class Issues: The proxy class may not be generated or may not match the expected configuration.
  Transport Issues: If the configuration was transported from another system, it may not have been transported correctly.
  
  Solution
  To resolve the error, you can follow these steps:
  
  
  Check Logical Port Configuration:
  
  Go to transaction SOAMANAGER.
  Navigate to the Web Service Configuration section.
  Check if the logical port specified in the error message exists and is correctly configured.
  If it does not exist, create a new logical port or modify the existing one to ensure it points to the correct endpoint.
  
  
  
  Verify Proxy Class:
  
  Ensure that the proxy class mentioned in the error message is correctly generated.
  You can check this in transaction SE80 (Object Navigator) or SE37 (Function Module) to see if the proxy class exists.
  
  
  
  Regenerate Proxy:
  
  If the proxy class is missing or incorrect, you may need to regenerate it.
  Use transaction SPROXY to regenerate the proxy classes for the web service.
  
  
  
  Check Transport Requests:
  
  If the configuration was transported from another system, ensure that all necessary transport requests were successfully imported and that there were no errors during the transport.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the web service call again to see if the error persists.
  
  
  
  Review Logs:
  
  Check the application logs (transaction SLG1) for any additional error messages that might provide more context about the issue.
