BR-CO-10: Line net amount sum mismatch

Ce que cela signifie

Sum of Invoice line net amount (BT-106) does not equal the sum of the individual Invoice line net amounts (BT-131).

Cause la plus fréquente

The header LineExtensionAmount was edited independently of the invoice lines (e.g. off by a rounding cent), or a line was added or removed without recalculating the header total.

Comment corriger

Recalculate LineExtensionAmount as the exact sum of all line net amounts at the source system and re-issue the invoice. Not auto-repaired: this is an arithmetic mismatch (CLAUDE.md invariant) and is reported expected-vs-found, never patched.
