PEPPOL-COMMON-R045 — E-Invoice Validation Rule & Fix

Fixture ID: peppolBadItalianCodes · XPath: /ubl:Invoice/cac:AccountingSupplierParty/cac:Party/cac:PartyIdentification/cbc:ID

1. Why This Rule Triggers (Diagnostic Message)

The Seller identifier (BT-29) is "123" under scheme "0210", which identifies the Italian Codice Fiscale. A value in that scheme must be either eleven digits (an organisation), or the sixteen-character personal layout: six letters, two digits, a letter, two digits, three characters, a digit and a letter, and this one is not. The Codice Fiscale is issued in two shapes — the eleven-digit form for organisations and the sixteen-character encoded form for individuals — and mixing them up usually means an individual's code was entered for a company or vice versa. Peppol flags this one as a warning rather than a rejection, so the document will be delivered — but a wrong identifier is delivered to the wrong place, or to nowhere. This is a Peppol BIS Billing 3.0 profile rule: it applies because profile is "peppol-bis-3". It does not apply to the en16931, xrechnung-ubl or xrechnung-cii profiles, whose validators will accept the same document.

2. How to Fix PEPPOL-COMMON-R045

Correct seller.identifier, or change its scheme identifier if the value belongs to a different register. A failing check digit or length almost always means a digit was transposed, dropped or added in transcription — compare it against the source register rather than re-typing it.
