What it means

For a charge on the whole invoice (BG-21), this rule checks ram:CategoryTradeTax/ram:TypeCode inside ram:SpecifiedTradeAllowanceCharge where ram:ChargeIndicator/udt:Indicator is true. This tax type is separate from the VAT category (BT-102). A non-empty value must be allowed by the profile's tax type code list. An empty value passes this code-list check.

Why it matters

The tax type identifies the tax to which the charge's category belongs. It is not the VAT category or the VAT rate.

How to fix it

Check the tax type assigned to your invoice charge. If you generate the XML yourself, set ram:CategoryTradeTax/ram:TypeCode to VAT in the header-level ram:SpecifiedTradeAllowanceCharge whose ram:ChargeIndicator/udt:Indicator is true. Generate the file again and recheck it.
