Hi,

Whenever someone changes a delivery (e.g. VL32N) a lock is created - lock object EVVBLKE.

Therefore you need to do the same in your program:

create lock (function module ENQUEUE_EVVBLKE) for the delivery you are working with

if you can set the lock, you can update the delivery (because no one else is updating it), if you can't set the lock (exception foreign_lock) then that delivery is currently processed by someone else and you just issue an error to the user that the delivery is locked.

If you get the lock, don't forget to unlock the delivery once your update is done. (function module DEQUEUE_EVVBLKE)

Hope that helps,

Michael
