Dear Yildirim, When we enable Validate Vat Totals on Entry in our own environment, I do not get the error, because we do not send a VAT amount, but a VAT code instead. When we do send a VAT amount, the following error appears: 'The VAT amount must be equal to the VAT total''. But this is a totally different error than expected. We are still wondering why 'Do you want the system to recalculate the amount(s) in the 'Cost' column?' appears, as it does not look like an error the API would return.... Hope you can help us further. Best, Jochem
