• What is the cause and solution for SAP error message M5138 - Selection version & locked by another user ?

  The SAP error message M5138, which states "Selection version & locked by another user," typically occurs when a user attempts to access or modify a selection version that is currently locked by another user. This can happen in various SAP transactions, particularly in the context of inventory management or material requirements planning (MRP).
  Cause:
  
  Concurrent Access: Another user is currently using or has locked the selection version you are trying to access. This can happen if multiple users are working on the same selection version simultaneously.
  Unreleased Locks: Sometimes, a lock may not be released properly due to a session crash or an unexpected termination of the transaction.
  Long-Running Transactions: If a transaction takes a long time to complete, it may hold the lock for an extended period, preventing others from accessing the selection version.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for a few moments and then retrying the operation may resolve the issue.
  Identify the Locking User: You can use transaction codes like SM12 (for lock entries) to identify which user is holding the lock on the selection version. This will help you understand if you need to wait or if you can contact the user to release the lock.
  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 in consultation with the user who holds the lock to avoid data inconsistencies.
  Check for Long-Running Transactions: If you suspect that a transaction is taking too long, you can check the system performance and see if any transactions can be optimized or if any users can be informed to complete their tasks.
  Communicate with Users: If you are in a collaborative environment, communicate with your team to ensure that everyone is aware of the selection versions they are working on to avoid conflicts.
