• What is the cause and solution for SAP error message CKMLRUN122 - Plant &1 is currently blocked by user &2 ?

  The SAP error message CKMLRUN122 indicates that a specific plant (denoted by &1) is currently blocked for processing by a user (denoted by &2). This typically occurs during the execution of a material ledger run or during the closing of periods in the Material Management (MM) module.
  Cause:
  The error is caused by the fact that another user is currently performing a task that locks the plant for processing. This could happen during:
  
  A material ledger closing run.
  A period-end closing process.
  A transaction that requires exclusive access to the plant's data.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Identify the User: Check who is currently blocking the plant. You can do this by using transaction codes like SM12 (to view lock entries) or SM21 (to check system logs).
  
  
  Communicate with the User: If possible, contact the user who is blocking the plant to understand what they are doing and when they expect to finish. Coordination can help avoid conflicts.
  
  
  Wait for Completion: If the blocking user is performing a necessary task, you may need to wait until they complete their work.
  
  
  Force Unlock (if necessary): If the blocking user is no longer active or if the lock is due to an error, a system administrator can manually remove the lock using transaction SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still processing.
  
  
  Check for Background Jobs: Sometimes, background jobs may also lock the plant. You can check for any running jobs using transaction SM37.
  
  
  Review Configuration: Ensure that the configuration for the material ledger and period-end closing processes is set up correctly to minimize locking issues.
  
  
  Related Information:
  
  
  Transaction Codes: 
  
  SM12: To view and manage lock entries.
  SM21: To view system logs.
  SM37: To monitor background jobs.
  
  
  
  Documentation: Refer to SAP Help documentation for more details on material ledger processes and period-end closing procedures.
  
  
  User Training: Ensure that users are trained on how to properly manage their tasks to avoid locking issues.
  
  
  By following these steps, you should be able to resolve the CKMLRUN122 error and proceed with your material ledger activities.
