Validation message

Invoice total VAT amount and Invoice total VAT amount in accounting currency MUST have the same operational sign

Explanation

The total VAT amount in the invoice currency and the one in the VAT accounting currency must have the same sign: both positive or both negative. Different signs point to a calculation or conversion error.

How to fix

Ask the seller for a corrected invoice in which both VAT totals have the same sign. This usually comes from the seller's invoicing software, not from data entry.
