Warning

CII-SR-341: Leave out the creditor reference type

In short

Warning: worth checking.

CII-SR-341 means the settlement section of the e-invoice contains a creditor reference type (CreditorReferenceType), which EN 16931 does not use. It is only a warning: remove it and keep the creditor identifier if you need one.

What it means

The settlement section (ApplicableHeaderTradeSettlement) should not contain a CreditorReferenceType, a description of what kind of creditor reference is given. The bank assigned creditor identifier (BT-90) used for direct debit is a separate element and is allowed.

Why it matters

This is a warning, so the file is still accepted. EN 16931 has no field for the type of a creditor reference, so receiving software normally ignores it. Nothing the buyer pays or books depends on it.

How to fix it

Remove the creditor reference type from the settlement section. If you collect payment by direct debit, check that the creditor identifier is still filled in under the payment details in your invoicing software. Fixing it is optional and mainly keeps the check clean. If the warning comes back, report it to the vendor of your invoicing software.
