In a Document level charge (BG-21) where the Document level charge VAT category code (BT-102) is "Exempt from VAT", the Document level charge VAT rate (BT-103) shall be 0 (zero).
A document level charge with VAT category Exempt from VAT (E) has a VAT rate (BT-103) that is not allowed: it must be exactly 0.
Set the rate to 0 and give an exemption reason (see the -10 rule). Or change the charge's category code so the two agree.
