• What is the cause and solution for SAP error message /SMB/SC_MAIN152 - Selection is locked by user &1 ?

  The SAP error message /SMB/SC_MAIN152 Selection is locked by user &1 typically indicates that a particular selection set or data set is currently locked by another user. This can happen in various scenarios, such as when a user is actively working with a report, transaction, or data entry that prevents others from accessing the same selection set simultaneously.
  Cause:
  
  Concurrent Access: Another user is currently using the selection set or report, which locks it for other users.
  Session Timeout: A previous session may not have been properly closed, leaving the selection set in a locked state.
  System Configuration: Certain configurations in the SAP system may enforce strict locking mechanisms to prevent data inconsistencies.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for the other user to finish their work may resolve the issue. You can try again after some time.
  Identify the Locking User: If you have the necessary permissions, you can check which user is holding the lock. This can be done using transaction codes like SM12 (to view lock entries) or SM21 (to check system logs).
  Contact the User: If you identify the user who is locking the selection, you can reach out to them to see if they can release the lock.
  Release the Lock: If the locking user is no longer active (e.g., due to a session timeout), an administrator can manually release the lock using transaction SM12.
  Check for Background Jobs: Sometimes, background jobs may also hold locks. You can check for any running jobs using transaction SM37.
  Review System Configuration: If this issue occurs frequently, it may be worth reviewing the system configuration and locking mechanisms to see if adjustments can be made.
