Answer Posted / lokesh
Lock object is a virtual link of several SAP tables which
is used to synchronize simultaneous access by two users to
the same set of data (SAP lock concept).
[or]
when two users simultaneously attempt to access the
same data record, this is cynchronised by a lock mechanism.
To set the locks,
you must define a lock object in ABAP dictionary. The name
of lock object should start with 'E'.
Thd Fun Modules for requesting and releasing lock which are
create automatically when the lock object is activated must
be linked to the programming of the relevant online
transactions.
They are 3 types:
1) write (exclusive lock)
2) read ( shared lock )
3) exclusive but not cummulative
Function modules :
1)ENQUEUE_FSFLIGHT (to lock the object)
2)DEQUEUE_FSFLIGHT (to unlock the object)
