CII-SR-483: The information amount may appear only once

What it means

The totals section (SpecifiedTradeSettlementHeaderMonetarySummation) can hold an extra amount in the element InformationAmount, given for information and not one of the totals that EN 16931 calculates with. EN 16931 has no business term for it, so most invoices do not carry it at all. The check allows it at most once.

Why it matters

If the same element appears twice, the recipient cannot tell which value is meant. This is a fatal error, so the invoice is rejected even though the figure itself is only information.

How to fix it

Work out whether anyone needs the figure. If not, remove InformationAmount from the totals; if so, keep one. A repeat is usually a fault in the software that exported the file, so if you cannot change the file yourself, ask the supplier to fix the export.

The rule as published

InformationAmount shall occur at most once in SpecifiedTradeSettlementHeaderMonetarySummation.
