Warning

CII-SR-351: Do not name a separate invoice recipient

In short

Warning: worth checking.

CII-SR-351 means the invoice has an InvoiceeTradeParty block, a party the invoice is addressed to when that is not the buyer, which EN 16931 does not use. Delete the block and put the business that should receive the invoice in the buyer details.

What it means

The invoice-level settlement section (ApplicableHeaderTradeSettlement) holds an InvoiceeTradeParty block. In the underlying syntax it names the party the invoice is addressed to when that differs from the buyer. EN 16931 only knows the buyer (BG-7), so the rule expects the block to be absent.

Why it matters

The file is still accepted, because this is a warning. Receivers treat the buyer as the party the invoice is addressed to and ignore the invoicee. If the invoicee is the business that should receive and book the invoice, the file is in effect addressed to the wrong one.

How to fix it

Delete the InvoiceeTradeParty block. Check the buyer details (BG-7) and the buyer's electronic address (BT-49): they should belong to the business that must receive and book the invoice. If invoices for a group go to a head office or a shared service centre, ask the buyer which business name and address they want on the invoice.
