What it means
Every charge on the whole invoice (BG-21) must contain the amount of the charge (BT-99). It is the amount of the charge without VAT.
Why it matters
Discounts and charges change the amount VAT is calculated on. The recipient needs the amount, the VAT category and the reason to book them correctly and to check that the VAT adds up.
How to fix it
Enter an amount for every charge in your invoicing software, or remove charges you do not use. An empty charge row, often left over from a template, triggers this rule.
The rule as published
Each Document level charge (BG-21) shall have a Document level charge amount (BT-99). Business terms: BG-21, BT-99
