• What is the cause and solution for SAP error message /SMB/SC_MAIN092 - Selection &1-&2 is locked by user &3 ?

  The SAP error message /SMB/SC_MAIN092 Selection &1-&2 is locked by user &3 indicates that a specific selection range (identified by the parameters &1 and &2) is currently locked by another user (identified by &3). This typically occurs in scenarios where multiple users are trying to access or modify the same data simultaneously, leading to a conflict.
  Cause:
  
  Concurrent Access: Another user is currently using the selection range, which prevents other users from making changes or accessing it.
  Session Lock: The selection might be locked due to an open session that has not been properly closed or released.
  Long-running Transactions: If a transaction is taking a long time to complete, it may hold locks on certain data, causing other users to encounter this error.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for the other user to finish their transaction may resolve the issue. You can try again after some time.
  Identify the Locking User: Use transaction code SM12 to check for locks in the system. You can look for the user ID mentioned in the error message to see what they are currently working on.
  Release the Lock: If you have the necessary authorizations, you can manually release the lock from transaction SM12. However, be cautious when doing this, as it may disrupt the other user's work.
  Communicate with the User: If possible, reach out to the user who is holding the lock to coordinate and resolve the issue.
  Check for Long-running Processes: If the locking is due to a long-running transaction, investigate and optimize the process if necessary.
