• What is the cause and solution for SAP error message K41C028 - Posting run &1 is already being processed by &2 ?

  The SAP error message K41C028, which states "Posting run &1 is already being processed by &2," typically occurs in the context of the Controlling (CO) module, particularly during the execution of a posting run for cost allocations or assessments. This error indicates that a posting run with the specified identifier (&1) is already in progress and is being processed by another user or session (&2).
  Cause:
  
  Concurrent Execution: The most common cause of this error is that the same posting run is being executed simultaneously by another user or process. SAP does not allow multiple instances of the same posting run to be processed at the same time to maintain data integrity.
  Session Lock: A session lock may be in place if a previous posting run did not complete successfully or was interrupted, leaving the system in a state where it thinks the run is still active.
  Long-Running Processes: If a posting run takes a long time to complete, it may lead to confusion if another user attempts to start the same run before the first one finishes.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the current posting run to complete. You can check the status of the posting run in the relevant transaction (e.g., KSV5 for assessments or KSV6 for distributions) to see if it is still running.
  Identify the User/Session: If you have access to transaction SM50 (Process Overview) or SM66 (Global Process Overview), you can identify the user or session that is currently processing the posting run. You may need to coordinate with that user to determine when they will finish.
  Terminate the Process: If the process is stuck or has failed, and you have the necessary authorizations, you can terminate the session using transaction SM50 or SM66. However, this should be done with caution and ideally after consulting with the user or your SAP Basis team.
  Check for Locks: Use transaction SM12 to check for any locks related to the posting run. If you find any locks that are no longer needed, you can delete them, but again, this should be done with caution.
  Review Logs: Check the application logs (transaction SLG1) for any additional information that might indicate why the posting run is stuck or if there were any errors during its execution.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KSV5 (Assessments), KSV6 (Distributions), SM50 (Process Overview), SM66 (Global Process Overview), and SM12 (Lock Entries).
  User Coordination: If multiple users are involved in the same posting run, establish a protocol to avoid concurrent executions.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address specific issues related to this error message or provide patches and updates.
  
  By following these steps, you should be able to resolve the K41C028 error and successfully complete your posting run.
