The SAP error message COWIPB316, which states "Batch &1 locked by another user," typically occurs when a user attempts to access or modify a batch that is currently locked by another user. This locking mechanism is in place to prevent data inconsistencies and ensure that batch processing is handled correctly.
Cause: Concurrent Access: Another user is currently working on the same batch, which causes the system to lock it to prevent simultaneous modifications. Long-running Transactions: A transaction that takes a long time to complete may hold the lock longer than expected. System Errors: Occasionally, system errors or crashes can leave a batch in a locked state even if the user is no longer actively using it.
Solution: Wait and Retry: The simplest solution is to wait for the other user to finish their transaction. You can periodically check if the batch is still locked. Identify the Lock: Use transaction code SM12 to view the list of locks
