BR-CO

The subset of EN 16931 business rules dedicated to calculations and conditions.

Definition

In the EN 16931 business-rule catalogue the prefix identifies the category: BR-* (presence of a term), BR-CO-* (calculations and conditions), BR-S/BR-Z/BR-E… (VAT consistency). BR-CO rules are enforced in Schematron: for example BR-CO-15 requires that the total amount with VAT (BT-112) equals the total without VAT plus the VAT amount. A violation produces a fatal error.

Origin

Defined in EN 16931-1 (Electronic invoicing — Semantic data model) by CEN/TC 434, and distributed as Schematron files by the European Commission and OpenPEPPOL.

Example in context

BR-CO-15: Invoice total amount with VAT (BT-112) = Invoice total amount without VAT (BT-109) + Invoice total VAT amount (BT-110).
