NL-R-009

Layer peppol·Checked against Peppol BIS Billing 3.0 2026.5

What does NL-R-009 mean? For suppliers in the Netherlands, if an order line reference (cac:OrderLineReference/cbc:LineID) is used, there must be an order reference on the document level (cac:OrderReference/cbc:ID)

Why did my invoice fail NL-R-009?

For suppliers in the Netherlands, if any invoice line uses an order line reference (cac:OrderLineReference/cbc:LineID), the document must also carry an order reference at document level (cac:OrderReference/cbc:ID). Line-level order references only make sense in the context of an identified order, so this Peppol BIS 3.0 Dutch country rule requires the header reference too.
