BR-12 — Missing sum of line net amounts

What it means

The sum of invoice line net amounts (total for goods/services) is missing. This field is the total of all line amounts, which the invoice total is then calculated from.

How to fix it

Check that the LegalMonetaryTotal section of the invoice XML has the LineExtensionAmount field filled in, and that it matches the sum of all lines (see also BR-CO-10).

Example

Wrong: the LineExtensionAmount element is missing. Correct: <cbc:LineExtensionAmount currencyID="EUR">500.00</cbc:LineExtensionAmount>.
