Lock-unlock order

[Former Member]

Hi all,

I thought we lock the record first, then process the function module, then unlock the record. Can someone explain why a program was written this way for posting movement for a production order ?

sy-subrc = 4

while sy-subrc ne 0.

Call FM 'ENQUEUE_ESORDER

endwhile.

Call FM 'DEQUEUE_ESORDER'

Data validation take place

Call FM 'BAPI_GOODSMVT_CREATE

COMMIT WORK

If the record is locked and then unlock immediately, how can it prevent the second user from accessing the same order ?

Any suggestions ?

thanks

The program is checking that the order has finished all previous updates and is unlocked.

Hi Rob,

That seems to make sense.
