EN 16931Error

The taxable amount (BT-116) of the VAT breakdown with category E (Exempt from VAT) must equal the sum of line net amounts (BT-131) minus document level allowances (BT-92) plus document level charges (BT-99) that carry category E. Recompute cbc:TaxableAmount / ram:BasisAmount from those lines; a line coded with another category or a forgotten allowance is the usual cause.
