CII-SR-344: Leave out the payment currency code

What it means

The settlement section (ApplicableHeaderTradeSettlement) should not contain a PaymentCurrencyCode. EN 16931 has one invoice currency (BT-5) for all amounts, and optionally a VAT accounting currency (BT-6). It has no separate currency for payment.

Why it matters

This is a warning, so the file is still accepted. Receiving software reads every amount in the invoice currency and normally ignores a payment currency. A buyer who expects to pay in another currency will not see it.

How to fix it

Remove the payment currency from the file and check that the invoice currency is correct. If VAT must be shown in a second currency, use the VAT accounting currency (BT-6). If you have agreed payment in another currency, say so in the payment terms (BT-20). Fix it when the amounts to pay differ from the invoice currency.
