Managing Lock Entries

Managing lock entries lets you monitor your system with regards to lock logic. You can determine which locks are being used currently. Locks that have had the backup flag set are highlighted in color (see Choosing and Displaying Lock Entries).

You can detect and correct problems by deleting locks that you no longer want. You can also later analyze the cause of lock table overflows using the history.

Integration

The SAP lock concept works closely with SAP Update.
