• What is the cause and solution for SAP error message WPRO_XI_PROXY060 - *** RFC Inbound Processing ("external call") ?

  The SAP error message WPRO_XI_PROXY060 typically occurs during the processing of inbound RFC calls in the context of SAP XI/PI (Exchange Infrastructure / Process Integration) proxy communication. This error is related to problems in the inbound processing of an external RFC call, often when a proxy interface is called from an external system or another SAP system.
  
  Cause
  The error WPRO_XI_PROXY060 usually indicates that the inbound RFC call to the proxy interface failed due to one or more of the following reasons:
  
  Incorrect or missing configuration of the inbound proxy or RFC destination.
  Mismatch in the interface or message structure between the sender and receiver proxy.
  Authorization issues for the user executing the inbound RFC call.
  Runtime errors in the proxy processing logic, such as exceptions in the generated proxy code.
  Communication or network issues causing the RFC call to fail.
  Missing or incorrect registration of the inbound proxy in the system.
  Version mismatch between the proxy runtime and the interface definition.
  
  
  Solution
  To resolve the WPRO_XI_PROXY060 error, follow these steps:
  
  
  Check the detailed error log:
  
  Use transaction SM58 (Transactional RFC Monitor) to check the inbound RFC queue and error details.
  Use transaction SLG1 (Application Log) to find detailed logs related to the proxy processing.
  
  
  
  Verify the proxy configuration:
  
  Ensure that the inbound proxy is correctly generated and activated in the system.
  Check the interface definition in the Enterprise Services Repository (ESR) or Integration Directory.
  Confirm that the proxy runtime is consistent with the interface version.
  
  
  
  Check the RFC destination:
  
  Use transaction SM59 to verify the RFC destination used for the inbound call.
  Test the connection to ensure it is working properly.
  
  
  
  Check authorizations:
  
  Verify that the user executing the inbound RFC call has the necessary authorizations.
  Check roles and profiles assigned to the user.
  
  
  
  Debug the proxy processing:
  
  If the error is due to runtime exceptions, debug the inbound proxy code.
  Use transaction SE80 or SE24 to check the generated proxy classes.
  Set breakpoints in the proxy methods to analyze the processing.
  
  
  
  Check for network or communication issues:
  
  Ensure that the network connection between sender and receiver systems is stable.
  Check for firewall or security settings blocking the RFC calls.
  
  
  
  Re-generate and re-import proxies:
  
  If there is a version mismatch or corruption, regenerate the proxy classes and re-import them.

  SAP Notes:
  
  Check SAP Notes related to proxy errors and inbound RFC processing.
  For example, SAP Note 1684845 (Proxy Runtime Errors) or others relevant to your SAP version.
  
  
  
  Proxy Runtime:
  
  The proxy runtime is part of the SAP NetWeaver stack and handles the serialization/deserialization of messages.
  Ensure the runtime is up to date and consistent with the interface definitions.
  
  
  
  Common Scenarios:
  
  Integration scenarios where an external system calls an SAP proxy via RFC.
  Cross-system communication using SAP XI/PI proxies.
