BR-CO-10 error
What this rule checks
Explanation
The invoice's line items must add up. This rule checks that the total net amount shown for all invoice lines together (the "Sum of Invoice line net amount", BT-106) exactly equals the sum of each individual line's net amount (BT-131) — the number in the totals section can't be produced by a different calculation than the lines it's supposed to summarize.
How to fix it
Recalculate the sum of all Invoice Line net amounts and compare it to the LineExtensionAmount used in LegalMonetaryTotal (UBL) or the LineTotalAmount in SpecifiedTradeSettlementHeaderMonetarySummation (CII). A mismatch is almost always a rounding difference or a stale total left over from manually editing a line after the totals were calculated — recompute the total from the current line amounts.
