A duplicate invoice check stops the same supplier bill being entered and paid twice.
What Sage X3 does on its own
On a purchase invoice you enter the supplier invoice number in the Supplier doc no. field (BPRVCR). X3 checks that the same number is not entered twice for the same invoicing supplier. The v12 help does not say whether it warns or blocks.
- Check is by number and supplier only.

Common questions
Does Sage X3 stop duplicate supplier invoice numbers?
Yes. The Supplier doc no. field (BPRVCR) is checked so the same number cannot be entered twice for the same invoicing supplier.
Is the supplier invoice number checked on Supplier BP invoices?
The same number check is described on Purchase invoices (field BPRVCR). The help for Supplier BP invoices says only that the Source document field records the invoice reference, so enter it every time.
Why do duplicates happen?
The same invoice arrives by email and post, a supplier resends it as a reminder, or two people enter it. A statement can also be keyed as a bill.
