The official message includes \"the\" before \"VAT category code\" and says \"net amounts\" in the plural. The published test compares category code K, adds the K charges and subtracts the K allowances from the K line net amounts, and requires the taxable amount to equal that sum. It does not allow a difference of less than 1. Each branch also requires an invoice line or a credit note line to exist.",
