• What is the cause and solution for SAP error message /AIF/RUNTIME029 - Processing of message &1 stopped; message already in process ?

  The SAP error message /AIF/RUNTIME029 Processing of message &1 stopped; message already in process typically occurs in the context of the Application Interface Framework (AIF) when a message is being processed more than once simultaneously. This can happen due to various reasons, such as:
  Causes:
  
  Concurrent Processing: The same message is being processed by multiple instances or threads at the same time.
  Message Locking: The message might be locked by another process, preventing it from being processed again until the lock is released.
  System Configuration: Configuration settings in AIF that allow for concurrent processing might not be set correctly.
  Error Handling: If a previous processing attempt failed and the message was not properly released or reset, it could lead to this error.
  
  Solutions:
  
  Check Message Status: Use transaction /AIF/MSG to check the status of the message. If it is still in processing, you may need to wait until it is completed.
  Review Logs: Look at the AIF logs to identify if there are any issues with the previous processing attempts that might have caused the message to be locked.
  Adjust Configuration: If concurrent processing is not required, consider adjusting the configuration settings in AIF to prevent multiple instances from processing the same message.
  Manual Intervention: If necessary, you can manually reset or release the message from processing using the appropriate AIF transaction or function module.
  Increase Lock Timeout: If the processing time is longer than expected, consider increasing the lock timeout settings to allow for longer processing times without conflicts.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /AIF/MSG for message monitoring and /AIF/CONF for configuration settings.
  Documentation: Refer to SAP Help documentation for AIF to understand the framework better and how to manage message processing.
  Performance Tuning: If this issue occurs frequently, consider reviewing the performance of the system and optimizing the processing logic to handle messages more efficiently.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis or AIF support team for further investigation and assistance.
