Hi,

There are associate function modules ENQUEUE/DEQUEUE.

This is get called when you are changing the rescord.

So when second person try to change the same record in the same table, it again tries to call the same function module.

Then the function module throws the exception 'Object already locked'.

Thanks,

'No if the user is entering the values using SM30 and the table is locked it does not give a message.'

I have given the wrong response.I had used a lock object for the same table and then tried to use SM30 and it worked.

But if you normally lock the table , you will get a message in SM30

I have picked this frm help...you can find out the user who has locked...

<b>Exceptions of the ENQUEUE Function Module

FOREIGN_LOCK: A competing lock already exists. You can find out the name of the user holding the lock by looking at system variable SY-MSGV1.</b>
