FAQ
When should I provide the Referenced purchase order line identifier (BT-132)?
Provide BT-132 when the buyer requires line-level PO matching, so each invoice line points back to a specific purchase order line. It is meaningful only when the order reference BT-13 is present at document level; without BT-13 there is no order for the line to reference.
What format does BT-132 use and how does it relate to BT-13?
BT-132 is a free-text line identifier (the order line number) matching how the buyer numbered lines on the purchase order referenced by BT-13. There is no fixed pattern in EN 16931, but the value must correspond to a real line in that order so the buyer can reconcile it.
