• What is the cause and solution for SAP error message CK520 - Costing run &1 locked by user &2. No selection possible ?

  The SAP error message CK520 indicates that a costing run is locked by another user, which prevents you from executing a new costing run or making selections related to that costing run. This typically occurs in the context of product costing in SAP, where multiple users may attempt to perform costing operations simultaneously.
  Cause:
  
  Concurrent Access: Another user is currently executing a costing run, which locks the process for other users.
  Incomplete Process: A previous costing run may not have been completed or was interrupted, leaving the system in a locked state.
  User Session: A user may have left their session open, which keeps the costing run locked.
  
  Solution:
  
  Wait for Completion: If another user is running the costing process, wait until they complete their task. You can check with your colleagues to see if they are currently working on it.
  Identify the Lock: Use transaction code SM12 to check for locks in the system. You can filter by the user ID mentioned in the error message to see if there are any active locks.
  Release the Lock: If you have the necessary authorizations, you can manually delete the lock entry in SM12. However, this should be done with caution and ideally after confirming with the user who holds the lock.
  Check for Incomplete Processes: If a previous costing run was interrupted, you may need to investigate and resolve any incomplete processes. This can involve checking logs or using transaction codes like CKR1 to review costing runs.
  Communicate with Users: If the lock is held by a user who is not actively working on the costing run, communicate with them to see if they can release the lock.
