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

1. Why This Rule Triggers (Diagnostic Message)

The VAT breakdown for category M at 10% states a VAT amount (BT-117) of 0.00 EUR on a taxable amount of 55.55, which at that rate is 5.56. BR-AG-09 allows a difference of strictly less than 1.00.

2. How to Fix BR-AG-09

Compute the group's VAT amount from its own taxable amount and rate, and check the rate matches the lines in the group.
