BR-CO
On this page
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).
