How to Retrieve Requester Department from HCM and Populate PO DFF Using VBS?

Hello Oracle Community,

I have a DFF field under Additional Order Details on the Purchase Order page.

Summary:

My requirement is to automatically populate this field with the Requester Department when the Purchase Order is created from a Purchase Requisition (PR).

I can identify whether the PO was created from a PR by checking the Requisition field under Related Documents. If the Requisition field contains a value, the PO originated from a PR; otherwise, it was created directly.

The Requester Department information is maintained in HCM, and I would like to populate it into the PO DFF using Visual Builder Studio (VBS).
