Hi Sandeep,

i guess you are referring to Optimistic Lock.

Check this link

Programming with Optimistic Locks

http://help.sap.com/saphelp_nw70/helpdata/EN/9a/49d91d498b4e489eef193e949db3f7/content.htm

Programming with optimistic locks is not yet supported in the Data Dictionary. You have to request the locks, as shown in the example program below:

There are the new modes O and R for the ENQUEUE function modules.

Check for the demo program for Optimisitc Locks in the link mentioned above.

SuryaD.

Hi Sandeep

Optimistic locks, or 'O' locks initially behave like shared locks and can be converted into exclusive locks.

An optimistic lock (mode 0) is set, if the user displays data in change mode. Optimistic locks on the same object cannot collide. If the user wants to save the (changed) data, the optimistic lock has to be converted into an exclusive lock (mode E). (This does not work, if beforehand another user has set a non-optimistic lock on the object). This procedure deletes other optimistic locks on the object.
