• What is the cause and solution for SAP error message RPM_APPL021 - IDocs being processed in background sessions ?

  The SAP error message RPM_APPL021 indicates that IDocs (Intermediate Documents) are being processed in background sessions. This typically occurs when there are issues with the processing of IDocs, which are used for data interchange between SAP systems and external systems.
  Cause:
  
  Background Processing: The IDocs are being processed in the background due to the configuration of the system or the way the IDocs are being sent. This can happen if the IDocs are not being processed in real-time or if there are too many IDocs queued for processing.
  System Load: High system load or performance issues can lead to delays in IDoc processing, causing them to be handled in background sessions.
  Configuration Issues: Incorrect configuration of the IDoc processing settings, such as the number of parallel processes allowed, can lead to this error.
  Error Handling: If there are errors in the IDocs themselves, they may be sent to the background for error handling or further processing.
  
  Solution:
  
  Monitor IDoc Processing: Use transaction codes like WE02 or WE05 to monitor the status of IDocs. Check for any errors or issues with the IDocs that are being processed.
  Check Background Jobs: Use transaction SM37 to check the status of background jobs. Look for any jobs related to IDoc processing and see if they are running as expected.
  Adjust Configuration: Review and adjust the configuration settings for IDoc processing. This may include increasing the number of parallel processes or adjusting the processing time settings.
  Error Resolution: If there are specific IDocs that are causing issues, resolve the errors in those IDocs. This may involve correcting data or reprocessing the IDocs.
