Hi Vipin,

You can quite simply use the lock object <b>ESRDIRE</b>.

<b>to lock

CALL FUNCTION 'ENQUEUE_ESRDIRE'

EXPORTING

MODE_TRDIR = 'E'

NAME = <i>Your Program name</i>

X_NAME = ' '

_SCOPE = '2'

_WAIT = ' '

_COLLECT = ' '

EXCEPTIONS

FOREIGN_LOCK = 1

SYSTEM_FAILURE = 2

OTHERS = 3

.

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.</b>

<b>to unlock use

CALL FUNCTION 'DEQUEUE_ESRDIRE'

EXPORTING

MODE_TRDIR = 'E'

NAME = <i>Your Program name</i>

X_NAME = ' '

_SCOPE = '3'

_SYNCHRON = ' '

_COLLECT = ' '

.</b>

Hope that helps!
