We have a few parts n the BOM that get assigned to a Job material listing that we don’t want to mass issue. Are there any settings that would prevent certain parts not to be mass issued?
I’m pretty sure backflushed parts and also materials that are flagged as make-direct on the job will not mass issue. But setting either one of those to a give part will have other ramifications… so I’m not saying those are workarounds in your case.
I’m guessing a BPM of some sort would be required to intervene on these parts’ behalf… but… can I ask why you want to prevent certain parts from mass issue and you want to manually issue them instead?
The whole idea of Mass Issue is to issue the planned job materials to the job/assembly in bulk.
