PEPPOL-COMMON-R044 — E-Invoice Validation Rule & Fix

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

1. Why This Rule Triggers (Diagnostic Message)

The Seller electronic address (BT-34) is "TOOLONG" under scheme "0201", which identifies the Italian IPA code (Codice Univoco Unità Organizzativa). A value in that scheme must be exactly six letters or digits, and this one is not. The IPA code addresses a specific organisational unit inside an Italian public body, and it is fixed-width. A value of any other length is usually the body's fiscal code pasted into the wrong field. 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-R044

Correct seller.electronicAddress, 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.
