Logs for Database Locks

Hi All,

One of my ztable did not get updated with the new entries using the UPDATE statement. This happend last week in one of our landscape systems. I assume that the ztable was locked during that instance since many users were updating the table via a webapplication.

Is there any log which I can pull out and see that this ztable was actually locked during that particular time.

I do know the exact time and date. Is there any t-code which can help me see the OLD lock details.

( The problem is I am not able to reproduce the same scenario now ).

Thanks

Yogesh
