What controls Inspection Required on POs?

We have decided not to use the Inspection Processing flag after having been live for a period of time. I have gone through and made sure all parts, part classes, and vendors have inspection processing turned off. Somehow it is getting turned back on when a PO is created. I have not been able to figure out what is causing some parts to have it turned on.

Is there another control somewhere that I may be missing that could still be turned on? Or is there something in Epicor that automatically turns it on when certain criteria are met?

If you have ‘Purchase Direct’ job materials, it can be flagged there.

I did notice that earlier today and I have disabled it so it can’t be accidentally checked.
