The SAP error message SAAB103 indicates that an activation table is currently locked by a specific user. This typically occurs when a user is trying to activate a table or a data dictionary object, but another user has already locked it for editing or activation.
Cause: Concurrent Access: Another user is currently working on the same table or object, which prevents other users from making changes or activating it. Long-Running Transactions: A transaction that is taking a long time to complete may hold the lock longer than expected. Unfinished Activation: An activation process may have been interrupted, leaving the table in a locked state.
Solution: Identify the Locking User: Check the user ID mentioned in the error message (e.g., &1). You can use transaction code SM12 to view the locks in the system. Contact the User: If possible, contact the user who is holding the lock to see if they can release it or complete their task. Release
