BR-12 Sum of Invoice line net amount is required

An invoice shall have the Sum of Invoice line net amount (BT-106), the total of all line net amounts before document allowances, charges and VAT.

This is an EN 16931 core rule. BT-106 is the starting point of the document totals: the sum of all line net amounts (BR-CO-10). In UBL, cbc:LineExtensionAmount in cac:LegalMonetaryTotal is optional in the schema, so an export that writes only the tax-exclusive and payable totals passes the schema and fails on BR-12. In CII, BT-106 is ram:SpecifiedTradeSettlementHeaderMonetarySummation/ram:LineTotalAmount.

Solution

Add cac:LegalMonetaryTotal/cbc:LineExtensionAmount equal to the sum of every line’s BT-131 net amount.
