What code is referencing the Processing Option in P4312 to update the Vend (Primary Supplier Number)

Hello All,

We have a custom application for Purchase Order Receipts. This application
is a copy of the JDE application P4312. We are in JDE 9.1. When performing a
Purchase Order Receipt, it is updating the Supplier Number (VEND) on the Item
Branch. The Processing Option Supplier Update Mode is set to Blank (Do not
update). There may be a difference in the code. Can anyone tell me where in the
code (in P4312) that references the Processing Option (Supplier Update Mode) to
update or not update the VEND on the Item Branch (F4102)?

Thank You.
