• What is the cause and solution for SAP error message WGDS_PROCESS655 - Enter an application for the inbound proxy process ?

  The SAP error message:
  WGDS_PROCESS655: Enter an application for the inbound proxy process
  
  Cause:
  This error occurs in the context of SAP PI/PO (Process Integration / Process Orchestration) or SAP Cloud Platform Integration when processing inbound proxy messages. The system expects an application to be specified for the inbound proxy process, but it is missing or not maintained.
  In other words, the integration engine or the inbound proxy runtime cannot determine which application or business system the inbound message belongs to because the application assignment is not maintained or configured properly.
  
  When does it occur?
  
  During inbound proxy message processing.
  When the integration engine tries to route or process the message but cannot find the application context.
  In scenarios where the inbound proxy is used to receive messages from external systems or other SAP systems.
  
  
  Solution:
  
  
  Maintain the Application in the Integration Directory:
  
  Go to the SAP PI/PO Integration Directory.
  Open the relevant Communication Component or Business System configuration.
  Ensure that the Application field is correctly maintained for the inbound interface or communication channel.
  
  
  
  Check the Inbound Proxy Configuration:
  
  In the SAP backend system (ECC, S/4HANA), check the inbound proxy configuration.
  Make sure the inbound proxy is correctly generated and the application is assigned.
  
  
  
  Verify the Integration Scenario:
  
  Confirm that the integration scenario is complete and all required parameters, including the application, are set.
  
  
  
  Check the ESR (Enterprise Services Repository):
  
  Verify that the service interfaces and message types are correctly assigned to the application.
  
  
  
  Re-generate the Proxy if Needed:
  
  If the proxy is outdated or incorrectly generated, regenerate the inbound proxy in the backend system.
  
  
  
  Check the Mapping and Routing Rules:
  
  Ensure that the routing rules or operation mappings in the integration flow or scenario specify the application correctly.
  
  
  
  
  Additional Information:
  
  The Application in SAP PI/PO context typically refers to the logical grouping or business application that processes the message.
  This error is related to message processing and routing in SAP middleware.
  Sometimes, this error can also occur if the integration engine cache is outdated; clearing the cache or restarting the integration engine might help.
