Any one using Coupa P2P software with Oracle AP / Payables? Want to know how / if Coupa has a defined solution for supporting Mexico's UUID requirements?

We use Coupa for Requisitions, PO's and AP invoice entry. We interface Coupa invoices into Oracle AP to produce payments and AP accounting entries.

We installed the Mexican Localization patches for Electronic Accounting - XML Files. (Release 12 Doc ID 1934128.1).  The patches installed Global DFF's in AP, AR and GL to support the entering / storing of the invoice UUID's, among other DFF's.

But because Coupa is our first source of AP invoice entry, the UUID for AP invoices would ideally need to be captured at the the source - in Coupa. And then interfaced into Oracle AP with the rest of the AP invoice details.
