CII-SR-406: Leave the partial payment amount out of the payment terms

What it means

The payment terms contain a PartialPaymentAmount element, the amount that is due under these terms, used to split a payment into instalments. EN 16931 does not use it. It has one due date (BT-9) and one amount due (BT-115) for the whole invoice.

Why it matters

This is a warning, so the invoice is still accepted. The buyer's software does not read the amount, so an instalment plan that only exists here is lost. It is worth fixing if you agreed instalments with the buyer, because they will not see them.

How to fix it

Remove the PartialPaymentAmount element. Write the instalments and their amounts in the payment terms text (BT-20). Keep the due date (BT-9) as the date by which the amount due has to be paid.
