  Cause:
  
  Concurrent Access: Another user is currently editing or viewing the customer record, which prevents other users from making changes until the lock is released.
  Long Transactions: A user may have a long-running transaction that has not yet completed, keeping the lock in place.
  System Issues: Occasionally, system issues or bugs can lead to locks not being released properly.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish their transaction and release the lock. You can try again after some time.
  Identify the Lock: Use transaction code SM12 to check for locks. You can see which user has locked the record and the details of the lock.
  
  In SM12, enter the customer number in the "User" field and execute. This will show you the locks related to that customer.
  
  
  Contact the User: If you identify the user who has the lock, you can contact them to see if they can release the lock.
  Release the Lock: If necessary and if you have the appropriate permissions, you can manually delete the lock in SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still working on the record.
  Check for System Issues: If locks are persisting longer than expected, it may be worth checking with your SAP Basis team to see if there are any underlying system issues or performance problems.
