EN 16931Error
For each VAT rate used with category L, the taxable amount (BT-116) of the matching VAT breakdown must equal the sum of line net amounts (BT-131) plus document level charges (BT-99) minus document level allowances (BT-92) that carry category L and that same rate (BT-152/BT-103/BT-96). A line with a different rate, a rounding difference or an allowance assigned to the wrong rate breaks this; recompute cbc:TaxableAmount / ram:BasisAmount per rate.
