IS-R-008

What does this rule mean?

The Icelandic final due date (EINDAGI) is not stated as YYYY-MM-DD.

The EINDAGI travels as a supporting document reference and must be a clean ISO date.

BT-122

Supporting document reference

Where the rule applies

Syntax: UBL

Affected element (XPath):

• ubl-creditnote:CreditNote[$SupplierCountry = 'IS'] | ubl-invoice:Invoice[$SupplierCountry = 'IS']

Technical test

The rule passes when this Schematron expression holds true:

(exists(cac:AdditionalDocumentReference[cbc:DocumentDescription = 'EINDAGI']) and string-length(cac:AdditionalDocumentReference[cbc:DocumentDescription = 'EINDAGI']/cbc:ID) = 10 and (string(cac:AdditionalDocumentReference[cbc:DocumentDescription = 'EINDAGI']/cbc:ID) castable as xs:date)) or not(exists(cac:AdditionalDocumentReference[cbc:DocumentDescription = 'EINDAGI']))

How to fix it

A missing or incorrect business entry only you can supply. Add or correct it, then re-check.

Write the EINDAGI as YYYY-MM-DD.

Correct the affected entry in your XML, then re-check the invoice. Validation runs locally in your browser — your file never leaves your machine.
