BR-06: Seller name (BT-27) is missing

Severity: fatal · Syntax: CII, UBL

Official message

An Invoice shall contain the Seller name (BT-27).

What this means

BT-27 is the RegistrationName of the seller's PartyLegalEntity. The UBL assertion checks normalize-space(cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName) != ''. A name only in PartyName does not satisfy this rule.

Typical cause

The trading name was exported, the registered name was not.

How to fix it

Put the registered name in RegistrationName.

UBL

<cac:PartyLegalEntity>
  <cbc:RegistrationName>Beispiel GmbH</cbc:RegistrationName>
</cac:PartyLegalEntity>

CII

<ram:SpecifiedLegalOrganization>
  <ram:TradingBusinessName>Beispiel GmbH</ram:TradingBusinessName>
</ram:SpecifiedLegalOrganization>
