  SAP Error Message:
  WXP711 Unexpected return code for & : &
  
  Meaning / Cause:
  
  This warning message occurs during the execution of a Web Dynpro application or when calling a Web Service.
  The message indicates that an unexpected return code (status code) was received from an external system or a backend service.
  The placeholders & : & are replaced at runtime with the name of the system or service and the actual return code received.
  Typically, this happens when the Web Dynpro component or the SAP system calls an external service (like a web service, RFC, or HTTP call) and the response code is not what was expected (e.g., HTTP 500 instead of 200, or an unexpected SAP return code).
  It can also occur if the external system is down, unreachable, or returns an error due to incorrect parameters or authorization issues.
  
  
  Common Causes:
  
  Network issues or connectivity problems between SAP and the external system.
  The external system or service is down or not responding properly.
  Incorrect configuration of the service endpoint or URL.
  Authorization or authentication failures.
  Incorrect or unexpected data sent to the external system.
  Timeout or communication errors.
  Backend system returns an error code that the SAP application does not expect or handle.
  
  
  Solution / Troubleshooting Steps:
  
  
  Check the Detailed Logs:
  
  Look into the SAP system logs (SM21), Web Dynpro traces, or the application log (SLG1) for more detailed error messages.
  Check the exact return code and message returned by the external system.
  
  
  
  Verify Connectivity:
  
  Use transaction SM59 to test the RFC or HTTP connection to the external system.
  Ensure the external system is reachable and responding.
  
  
  
  Check Service Configuration:
  
  Verify the service URL, endpoint, and parameters configured in the SAP system.
  Confirm that the service is active and the URL is correct.
  
  
  
  Authorization:
  
  Ensure that the user or system making the call has the necessary authorizations on the external system.
  Check for any authentication tokens or certificates if applicable.
  
  
  
  Analyze the Return Code:
  
  Identify what the unexpected return code means in the context of the external system.
  For HTTP calls, check if it is a 4xx or 5xx error and troubleshoot accordingly.
  For RFC or SOAP calls, check the error messages returned.
  
  
  
  Check for Patches or Notes:
  
  Search SAP Notes for WXP711 or related Web Dynpro or Web Service issues.
  Apply any relevant SAP Notes or patches.
  
  
  
  Debugging:
  
  If possible, debug the Web Dynpro application or the function module making the call to see where the unexpected return code is generated.
