locking master table while in 'Change' mode for screen program

Former Member — Thu, 25 Sep 2008 16:34:54 GMT

Hi I have built a custom screen, I have change/display buttons on my screen. While in 'Change' mode in the screen, I need the tables used in the program to be locked from any changes made to them. How can I do this?

Search for lock objects of those tables

i.e. ENQUEUE_lockobject and DEQUEUE_lockobject for locking and unlocking respectively

and use them accordingly in your code

Alright I've created the lock object but it doesnt seem to be working... I created the lock 'EZLOCK' and have called the function module in my user_command input like so:

CALL FUNCTION 'ENQUEUE_EZLOCK'

EXPORTING

MODE_ZDSTATS_COPY = 'E'

MANDT = SY-MANDT

ZYEAR = zdstats_copy-zyear

ZTEAM = zdstats_copy-zteam

X_ZDPLAYER_ID = ' '
X_ZYEAR = ' '
X_ZTEAM = ' '
_SCOPE = '2'
_WAIT = ' '
_COLLECT = ' '

EXCEPTIONS

FOREIGN_LOCK = 1

SYSTEM_FAILURE = 2

OTHERS = 3.

Nothing unfortunately is locking, am i doing something wrong?
