What it means
When a charge on the whole invoice has VAT category O (not subject to VAT), it must not contain a VAT rate (BT-103) at all.
Why it matters
An amount outside the scope of VAT has no rate, not even zero. Zero rated is a different category (Z), so a rate here makes the VAT treatment ambiguous and the invoice is rejected.
How to fix it
In your invoicing software, set the item or line to the category "not subject to VAT" without a percentage. If your software always writes a rate, check for a separate option for supplies outside the scope of VAT, or ask your software provider. In UBL, leave out cbc:Percent in that tax category.
The rule as published
A Document level charge (BG-21) where the VAT category code (BT-102) is "Not subject to VAT" shall not contain a Document level charge VAT rate (BT-103). Business terms: BG-21, BT-102, BT-103
