CII-SR-273: Buyer electronic address should not carry a channel code

What it means

The buyer's electronic address (BT-49), where the buyer receives e-invoices, is written with an extra ChannelCode element beside the address. EN 16931 only uses the address itself and its scheme identifier, so the channel code should not be there.

Why it matters

This is only a warning, so the file is still accepted. The scheme identifier already says what kind of address it is, such as EM for an email address, so the channel code adds nothing the buyer's software uses.

How to fix it

In your invoicing software, open the buyer's e-invoice or electronic address settings on the customer record. Keep the address and its scheme, and remove any channel or communication type field, or stop it being exported. If you build the XML yourself, delete the ChannelCode element from the buyer's URIUniversalCommunication.
