What does this mean?

If the seller has a tax representative (Seller tax representative party, BG-11), its name (Seller tax representative name, BT-62) must be provided in the invoice. The group exists, the name is missing.

Typical causes

Only address or VAT identifier were given for the tax representative, but no name.
The tax representative group was created although there is no tax representative.

How to fix the error

Enter the tax representative's name.
If there is no tax representative, omit the group BG-11 entirely.
CII: ram:ApplicableHeaderTradeAgreement/ram:SellerTaxRepresentativeTradeParty/ram:Name, UBL: cac:TaxRepresentativeParty/cac:PartyName/cbc:Name.
Generate and validate the invoice again.

In E-Rechnungsfreund

In the invoice form ("Experte" view), section "Steuervertreter (BG-11)" (tax representative), fill in the field "Name (BT-27/44)". If there is no tax representative, clear the checkbox "Steuervertreter angeben" (state a tax representative).
