BR-62

Where the seller electronic address (BT-34) is sent, it must carry a scheme identifier. The attribute says which register the identifier comes from — without it the value is only a string.

Official rule text

The Seller electronic address (BT-34) shall have a Scheme identifier.

Why does BR-62 happen?

The address is mapped as a plain string, because in the source system it is one. The scheme attribute beside it has no counterpart there and stays empty.

How do you fix BR-62?

Set the schemeID attribute on cac:AccountingSupplierParty/cac:Party/cbc:EndpointID in UBL, and the corresponding schemeID on the same element in CII. PEPPOL-EN16931-R020 requires the address itself.

In the XML

A UBL fragment. The CII path is named above — same change, different element names.
