UBL-CR-468: Do not put an exchange rate in the payment terms

What it means

The rule warns when the payment terms block (cac:PaymentTerms) of the invoice or credit note holds a cac:ExchangeRate, a conversion rate between two currencies. An EN 16931 invoice is in one currency (BT-5). The only second currency it allows is for the VAT total, through the VAT accounting currency (BT-6) and the total VAT amount in that currency (BT-111).

Why it matters

EN 16931 does not use cac:ExchangeRate in cac:PaymentTerms.

How to fix it

Remove the exchange rate and check that amounts are in the invoice currency, except any VAT total in the VAT accounting currency (BT-111). If the tax rules require VAT in a second currency, fill in the VAT accounting currency code (BT-6) and the VAT total in that currency (BT-111). If the buyer is to pay in another currency at an agreed rate, say so in the payment terms text (BT-20). In the XML, delete cac:ExchangeRate from cac:PaymentTerms. Check the corrected file again.
