BR-NL-13: Order line references need a purchase order number on the invoice

What it means

When an invoice line gives the number of a purchase order line (BT-132), the invoice as a whole must also give the purchase order number (BT-13). The rule is checked for each line that has an order line reference.

Why it matters

An order line number only means something together with the order it belongs to. Without the order number the recipient cannot match the line, so the file fails the check and the invoice is rejected.

How to fix it

Enter the buyer's purchase order number in the order reference field in the invoice header, not on the lines. If you do not have an order number, clear the order line references from the lines instead. Then export the file again.

The rule as published

If an order line reference (BT-132) is used, there must be an order reference on the document level (BT-13)

Business terms: BT-13, BT-132
