The Item standard identifier (BT-157) 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:InvoiceLine/cac:Item/cac:StandardItemIdentification/cbc:ID | cac:CreditNoteLine/cac:Item/cac:StandardItemIdentification/cbc:ID

CII

  • //ram:IncludedSupplyChainTradeLineItem

Technical test

The rule passes when this Schematron expression holds true:

normalize-space(ram:SpecifiedTradeProduct/ram:GlobalID/@schemeID) != '' or not (ram:SpecifiedTradeProduct/ram:GlobalID)
