• What is the cause and solution for SAP error message /SDF/IVIS_DC_MSG021 - IDoc processed but has not left system (still in tRFC layer) ?

  The SAP error message /SDF/IVIS_DC_MSG021 indicates that an IDoc (Intermediate Document) has been processed but has not yet left the system, meaning it is still in the tRFC (Transactional Remote Function Call) layer. This situation can occur for various reasons, and understanding the cause and potential solutions is essential for troubleshooting.
  Causes:
  
  tRFC Queue Issues: The tRFC queue may be blocked or experiencing issues, preventing the IDoc from being sent to the target system.
  Network Issues: There may be network connectivity problems between the SAP system and the target system, causing delays in processing.
  Configuration Issues: Incorrect configuration settings for the IDoc processing or the RFC destination can lead to this error.
  System Performance: High system load or performance issues can delay the processing of IDocs.
  Error in the IDoc: There may be errors in the IDoc data itself that prevent it from being processed correctly.
  
  Solutions:
  
  
  Check tRFC Queue:
  
  Use transaction SM58 to check the tRFC queue for any entries that are stuck or have errors. If you find entries, you can analyze the error messages and take appropriate action.
  If necessary, you can manually reprocess the entries.
  
  
  
  Monitor IDoc Status:
  
  Use transaction WE02 or WE05 to monitor the status of the IDocs. Check if there are any errors or if they are still in the "processed" state.
  
  
  
  Check RFC Destination:
  
  Verify the configuration of the RFC destination used for sending the IDoc. Use transaction SM59 to check the settings and ensure that the destination is correctly configured and reachable.
  
  
  
  Network Connectivity:
  
  Ensure that there are no network issues between the SAP system and the target system. You can use tools like ping or traceroute to check connectivity.
  
  
  
  System Performance:
  
  Monitor system performance using transaction ST22 for dumps, SM50 for active processes, and SM66 for global work processes. If the system is under heavy load, consider optimizing performance.
  
  
  
  Check for IDoc Errors:
  
  If the IDoc has errors, you can use transaction WE19 to test and simulate the IDoc processing. This can help identify any data-related issues.
  
  
  
  Review Application Logs:
  
  Check application logs using transaction SLG1 for any relevant error messages that might provide more context on the issue.
  
  
  
  Related Information:
  
  IDoc Processing: Understanding how IDocs are processed in SAP can help in troubleshooting. IDocs are typically processed in a background job, and any issues in this job can lead to delays.
  tRFC Mechanism: Familiarize yourself with how tRFC works, including its role in ensuring that remote function calls are executed reliably.
  SAP Notes: Check for any relevant SAP Notes that might address known issues related to IDoc processing and tRFC.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to ensure that the IDoc is processed and sent successfully.
