Warning

CII-SR-243: Seller contact should not have a nested contact person

In short

Warning: worth checking.

CII-SR-243 means the seller's contact details include a SpecifiedContactPerson element, a second person nested inside the contact, which EN 16931 does not use. It is only a warning: delete it and keep one contact name.

What it means

In a CII file, the seller's contact (BG-6) is the DefinedTradeContact block, with one contact name (BT-41), phone number (BT-42) and email address (BT-43). This rule warns when the block also contains a SpecifiedContactPerson element.

Why it matters

This is a warning, so the invoice is still accepted. The standard only has one contact point for the seller, so the buyer's software will normally ignore the nested person.

How to fix it

Decide who the buyer should contact and make that name the seller's contact name in your invoicing software. Stop the nested person from being exported. In hand-edited XML, delete the SpecifiedContactPerson element inside the seller's DefinedTradeContact.
