Problem of FM ENQUEUE_EVVBLKE return code 2.

[Former Member]

The delivery picking program is customizing. I used FM 'ENQUEUE_EVVBLKE' in order to lock the delivery no. before picking. I also used FM 'DEQUEUE_EVVBLKE' after the user finish picking the delivery. But the delivery still be locked if another user run the same program again. The return code of the FM 'ENQUEUE_EVVBLKE' is 2. That's why? Thanks!

The codes are as follows:

• lock delivery

CALL FUNCTION 'ENQUEUE_EVVBLKE'

EXPORTING

MODE_LIKP = 'E'

MANDT = SY-MANDT

vbeln = v_vbeln

EXCEPTIONS

foreign_lock = 2

system_failure = 3.

*unlock delivery

CALL FUNCTION 'DEQUEUE_EVVBLKE'

EXPORTING

MODE_LIKP = 'E'

MANDT = SY-MANDT

VBELN = v_vbeln.

• X_VBELN = ' '

• _SCOPE = '3'

• _SYNCHRON = ' '

• _COLLECT = ' '

Hi,

put a break-point on CALL FUNCTION 'DEQUEUE_EVVBLKE' and check if it is always reached and if the value of v_vbeln is the same as at the point of calling FM 'ENQUEUE_EVVBLKE'. Also check if no 'ENQUEUE_EVVBLKE' is called after 'DEQUEUE_EVVBLKE' for the same v_vbeln. If these things are ok, try to call dequeue function module with SYNCHRON = 'X'. You can also check locks in transaction SM12 after call of DEQUEUEEVVBLKE.

Hi,

You can try the following too:

CALL FUNCTION 'ENQUEUE_E_TABLE'

EXPORTING

MODE_RSTABLE = 'X'

TABNAME = 'EVVBLKE'.

CALL FUNCTION 'DEQUEUE_E_TABLE'

EXPORTING

MODE_RSTABLE = 'X'

TABNAME = 'EVVBLKE'.
