Hiii

I have an enhancement that have been implement at the end of a creation of an inbound deliveries.

My requirement is as follow

After the creation of the inbound deliveries after the commit of the delviery, I call a FM BAPI_BATCH_CREATE to create batch etc..

The issue i am having is that suppose i am creating 2 delivery

for the first delivery the FM fail BAPI_BATCH_CREATE and this is cause by an collision in enqueue EMMARCS. I saw that in ST05

For the second delivery this work fine

I wanted to correct the error by

by checking before the calling of the FM BAPI_BATCH_CREATE if enqueue EMMARCS fail i dequeue it. But i think there may be regressing since the program may be updating something in MARCS and i am throwing it out because of My dequeue?

Please advise

Use BAPI_TRANSACTION_COMMIT after BAPI_BATCH_CREATE.

Hi,

When there are situations where parallel updates are happening, i usually do a wait to allow significant time for the first process to complete.

Do 5 times.

CALL <ENQUEUE>

IF locked

if cnt eq 5

call <Dequeue>

exit.

else.

cnt = cnt + 1.

Continue.

endif

ELSE.

EXIT.

ENDIF.

ENDDO.

Hope this helps.

Regards,

San
