BR-13

The invoice must contain the total amount without VAT (BT-109). The norm requires each of the totals explicitly — none of them may be left to be inferred from the others.

Official rule text

An Invoice shall have the Invoice total amount without VAT (BT-109).

Why does BR-13 happen?

Where there are no document-level allowances or charges, this looks identical to the line sum, and only one of the two gets written.

How do you fix BR-13?

Write BT-109 into cac:LegalMonetaryTotal/cbc:TaxExclusiveAmount in UBL, or ram:SpecifiedTradeSettlementHeaderMonetarySummation/ram:TaxBasisTotalAmount in CII. How the value has to agree with the other totals is covered by BR-CO-10 through BR-CO-16.
