BR-CL-21 — E-Invoice Validation Rule & Fix

Fixture ID: badStandardItemScheme · XPath: /ubl:Invoice/cac:InvoiceLine[1]/cac:Item/cac:StandardItemIdentification/cbc:ID/@schemeID

1. Why This Rule Triggers (Diagnostic Message)

Line 1 declares the item standard identifier scheme "9930" (BT-157-1), which is not in the ISO 6523 ICD list. Note that the scheme here is an ICD code, not the name of the numbering system: "GTIN", "EAN" and "UPC" all fail, however unambiguous they read, because the attribute holds a registry code rather than a label. BR-64 checks that a scheme is present at all; this rule checks that the one you gave exists.

2. How to Fix BR-CL-21

Set line.standardItemId.schemeId to the ISO 6523 ICD code of the registry — "0160" for a GTIN, "0088" for a GLN-based article number, "0060" for a D-U-N-S-based one. If your identifier is not from a registered scheme, move it to line.sellerItemId (BT-155), which needs no scheme.

"standardItemId": { "schemeId": "0160", "value": "04012345678901" }
