The Buyer electronic address (BT-49) shall have a Scheme identifier.

Where the rule applies

Syntax: CII · UBL

The same rule, expressed twice: UBL and CII name the same fields with different paths. Running a CII file against the UBL rules is why you get errors that mean nothing.

UBL

  • cac:AccountingCustomerParty/cac:Party/cbc:EndpointID

CII

  • /rsm:CrossIndustryInvoice

Technical test

The rule passes when this Schematron expression holds true:

normalize-space(rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeAgreement/ram:BuyerTradeParty/ram:URIUniversalCommunication[1]/ram:URIID/@schemeID) != '' or not (rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeAgreement/ram:BuyerTradeParty/ram:URIUniversalCommunication)
