What does this mean?

Every invoice must contain the buyer name (BT-44), the full name of the invoice recipient. The element is missing or contains only spaces.

Typical causes

The buyer name was not entered.
Only a contact person or department was given, but not the buyer name.
UBL: The name only appears in cac:PartyName, not in the legal name cac:PartyLegalEntity/cbc:RegistrationName.

How to fix the error

Enter the full buyer name.
CII: ram:ApplicableHeaderTradeAgreement/ram:BuyerTradeParty/ram:Name, UBL: cac:AccountingCustomerParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName.
Generate and validate the invoice again.

In E-Rechnungsfreund

In the invoice form, section "Käufer (BG-7)" (buyer), fill in the field "Name (BT-27/44)".
