Hi Charan,

Lock Objects are of three types.

Exclusive, cumulative

Shared

Exclusive, not cumulative

These are used to lock a record based on the lock mode

When a Lock object is created and activated it

generates function modules that set and release locks

hi Charan,

A lock object definition contains the database tables and their key fields on the

basis of which you want to set a lock...

When you create a lock object, the system automatically

generates two function modules with the names ENQUEUE_<lock object name> and

DEQUEUE_<lock object name>...

You can then set and release SAP locks in your ABAP

program by calling these function modules in a CALL FUNCTION statement...

Unlike the database, which sets physical locks, the SAP lock mechanism sets logical locks...

A locked database entry is not physically locked in the database table.

The lock entry is merely entered as a lock argument in the central R/3 lock table...

can you kindly close your previous and reward the helpful answers..
