Security on Part Maintenance (not authorized to update...)

I have Part Maintenance available in the Purchasing + Setup but when my purchasing folk attempt to change non-stock on the Plant tab they get a "not authorized to update nonstock field"

When they change Vendor on the same form they get "Column "VendorID" does not belong to table PartPlant.

The PartMaintenance form has been customized but not this tab. Any clues? Did we miss a setup step somewhere. I looked at field security but nothing different there.
