• What is the cause and solution for SAP error message CKMLRUN121 - The costing run is blocked by user &1 ?

  The SAP error message CKMLRUN121 indicates that a costing run is blocked by a specific user. This typically occurs in the context of Material Ledger and costing processes, where a costing run is initiated but cannot proceed because another user has locked it.
  Cause:
  
  User Lock: The most common cause is that another user is currently processing a costing run, which prevents other users from starting a new costing run until the first one is completed or released.
  Incomplete Process: If a previous costing run was not completed properly (e.g., due to a system crash or user interruption), it may leave the costing run in a locked state.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to unlock or view the status of the costing run.
  
  Solution:
  
  Check Active Costing Runs: Use transaction code CKMLCP (or CKMLRUN) to check if there are any active costing runs. If you find one that is being processed by another user, you may need to wait until that user completes their run.
  Identify the User: The error message specifies the user that is blocking the costing run. You can communicate with that user to understand their progress and whether they can complete or release the run.
  Unlocking the Costing Run: If you have the necessary authorizations, you can unlock the costing run. This can be done through transaction code SM12, where you can view and delete the lock entries associated with the user.
  System Administrator Intervention: If the issue persists and you cannot resolve it, you may need to involve a system administrator to check for any underlying issues or to forcibly release the lock if necessary.
  Review Logs: Check the system logs for any errors or warnings that might provide additional context about why the costing run is blocked.
