Peppol BIS Billing 3.0.21 · UBL
Original rule text
[BR-56]-Each Seller tax representative party (BG-11) shall have a Seller tax representative VAT identifier (BT-63).
exists(cac:PartyTaxScheme[cac:TaxScheme/(normalize-space(upper-case(cbc:ID)) = 'VAT')]/cbc:CompanyID)BR-56 is a fatal rule in the business layer of Peppol BIS Billing 3.0.21 · UBL. An invoice that breaks it is rejected. It refers to BG-11, BT-63.
What this rule requires
The rule requires that every seller tax representative party (BG-11) present in the invoice has a seller tax representative VAT identifier (BT-63). In UBL, the cac:TaxRepresentativeParty must contain a cac:PartyTaxScheme whose cac:TaxScheme/cbc:ID equals 'VAT' (ignoring case and surrounding spaces) and whose cbc:CompanyID is present. In CII, the ram:SellerTaxRepresentativeTradeParty must contain a ram:SpecifiedTaxRegistration with an ram:ID that has @schemeID='VA' and a non-empty value (not just whitespace).
How to fix
If the seller tax representative party exists, add the missing VAT identifier. In UBL, within cac:TaxRepresentativeParty, add a cac:PartyTaxScheme with cac:TaxScheme/cbc:ID set to 'VAT' and cbc:CompanyID containing the VAT identifier. In CII, within ram:SellerTaxRepresentativeTradeParty, add a ram:SpecifiedTaxRegistration with ram:ID having @schemeID='VA' and a non-empty value. Ensure the identifier is not empty or only whitespace in CII.
