Hi,

There are two function modules used to lock and unlock the tables. Those are mentioned below.

Unlocking the table

CALL FUNCTION 'DEQUEUE_E_TABLE'

EXPORTING

tabname = table_name

locking the table

CALL FUNCTION 'ENQUEUE_E_TABLE'

EXPORTING

tabname = table_name

EXCEPTIONS

foreign_lock = 1

system_failure = 2

OTHERS = 3.

Hi,

whenevere we create lock object for perticular table, it will generate two function mudules.

those function module are 'ENQUEUE_E_TABLE' and 'DEQUEUE_E_TABLE'.

if you want to lock the table, you can use below function module

CALL FUNCTION 'ENQUEUE_E_TABLE'

EXPORTING

tabname = table_name

EXCEPTIONS

foreign_lock = 1

system_failure = 2

OTHERS = 3.

if you want to release the table, you can use below function module

CALL FUNCTION 'DEQUEUE_E_TABLE'

EXPORTING

tabname = table_name

thanks
