BR-O-09 — E-Invoice Validation Rule & Fix

Fixture ID: documentGroupVatWrongO · XPath: /ubl:Invoice/cac:TaxTotal/cac:TaxSubtotal/cbc:TaxAmount

1. Why This Rule Triggers (Diagnostic Message)

The VAT breakdown for category O states a VAT amount (BT-117) of 5.00 EUR. BR-O-09 requires it to be exactly 0: category O charges no VAT, and no tolerance applies.

2. How to Fix BR-O-09

Set the group's VAT amount to 0.00. If VAT is really due on these lines, their category is not O.
