JDE E1 9.2.8.5 JPD920 Payment Terms on Application P4310 Form W4310E Version FCC0017

Is there a processing option which allows payment terms to be updated on Application P4310 Form W4310E Version FCC0017? I am getting a blanks invalid error which is Net 30 when trying to update the PO payment terms. In our training environment, it allows the change, not in our production environment. Compared Processing options in IV application P983051 Form W983051I and they appear to be the same. Not sure where else to look. Checked P0014 and blank payment terms is setup. In P04012 the vendor shows blank (net 30) payment terms as well.

thank you.
