Hi Swapna,

1)Create a lock object, suppose EZLOCK in SE11 for the table
ZLOCK (having fields..field1, field2, field3).

2)Activate it, system will automatically generates two
function modules for locking and unlocking.

3) How to use them in program ?
Here you go..

loop at itab into wa_tab.
* For Locking the table ZLOCK
CALL FUNCTION 'ENQUEUE_EZLOCK'
EXPORTING
mode_ZLOCK = 'E'
mandt = sy-mandt
field1 = wa_zlock-field1
field2 = wa_zlock-field2
field3 = wa_zlock-field3
EXCEPTIONS
foreign_lock = 1
system_failure = 2
OTHERS = 3.

* For Unlocking the table ZLOCK
CALL FUNCTION 'DEQUEUE_EZLOCK'
EXPORTING
mode_ZLOCK = 'E'
mandt = sy-mandt
field1 = wa_zlock-field1
field2 = wa_zlock-field2
field3 = wa_zlock-field3

endloop.
