OMJ3 configuration not picked up in spool request

Hi all,

I have configured the printer determination for an message output for 261 movements. When I check the testing data, one of the material doc, the message output shows the OMJ3 output type and printer being selected.

However, when i go to the spool's request, the spool request picks up the printer defaulted in my user's profile(SU3 transaction) instead.

When i remove the default printer in user's profile and perform a re-print, no spool request is created at all.

Seems that the printing of the GI slip seems to bypass the configuration at all, but strangely the material doc is picking up the output type and printer correctly.

Can anyone advise what could be the root cause for this? thanks.
