StandardEN 16931-1 (European e-invoicing semantic model)SeverityError: the invoice is rejectedSyntaxUBL, CIIApplies toEvery EN 16931 invoice: XRechnung, ZUGFeRD 2.x / Factur-X (profiles EN 16931, EXTENDED, XRECHNUNG), Peppol BIS Billing 3.0, and national CIUS such as the Dutch NLCIUS or the Italian/Spanish profiles.

Official rule text

[BR-CL-26] Delivery location identifier scheme identifier MUST belong to the ISO 6523 ICD code list

Why this error occurs

The value must come from a fixed code list and the value in your file is not on it. Common causes: a free-text value instead of a code ("Invoice" instead of 380), a code from an older list version, lower-case codes, or a code valid in another standard but not in this one.

How to fix it

Replace the value with a code from the list named in the rule text (UNTDID 1001 for document types, UNTDID 5305 for VAT categories, ISO 4217 for currencies, ISO 3166-1 for countries, UN/ECE Recommendation 20/21 for units, EAS for electronic addresses, ISO 6523 ICD for scheme identifiers). Codes are case-sensitive.
