BR-36 — E-Invoice Validation Rule & Fix

Fixture ID: chargeEmpty · XPath: /ubl:Invoice/cac:AllowanceCharge[1]/cbc:Amount

1. Why This Rule Triggers (Diagnostic Message)

The document level charge at charges[0] has no usable charge amount (BT-99): you supplied missing. Each BG-21 group must have one, because it is the only figure that actually moves money — the percentage (BT-101) and base amount (BT-100) are documentation of how the figure was reached, not substitutes for it, and BT-108 is the sum of these amounts under BR-CO-12.

2. How to Fix BR-36

Set charges[0].amount to a positive number of EUR — always positive, even for an allowance: it is the array the entry sits in, not its sign, that decides whether the figure is deducted or added.
