What do the DueDateTypeCode values mean?

UNTDID 2005 codes: 5 = invoice date, 29 = delivery date, 72 = payment date. These control which date becomes the VAT tax point.

Why cannot I use different codes per line?

VAT is reported at invoice level. One invoice belongs to one VAT reporting period, and DueDateTypeCode decides which period that is.

Is this error auto-fixable?

No. Choosing which DueDateTypeCode applies is a VAT policy decision. Invoice Navigator surfaces the current values and asks the caller to confirm which one should apply.

Can I just remove DueDateTypeCode entirely?

Yes if the CIUS does not mandate it. DE XRechnung and FR Factur-X BASIC accept invoices without it; IT split-payment requires DueDateTypeCode=72.

Which CIUS layers enforce CII-SR-462?

Every CIUS that inherits from the shared EN 16931 CII Schematron: XRechnung, Factur-X, Peppol BIS CII, and all ZUGFeRD profiles from BASIC upwards.

CII-SR-462Fixable here

Only one DueDateTypeCode may be present across all tax breakdown entries

This is the rejection, word for word: „[CII-SR-462] CII-SR-462 is a fatal EN 16931 syntax rule on the CII binding. It asserts that across every ram:ApplicableTradeTax block in the document, either no ram:DueDateTypeCode is present, or every DueDateTypeCode carries the same value. The XPath test is count(//ram:ApplicableTradeTax/ram:DueDateTypeCode)=0 or count(distinct-values(//ram:ApplicableTradeTax/ram:DueDateTypeCode))=1.“

What to have readyThe missing value from your purchase order, contract or bookkeeping.

What we doPick a single DueDateTypeCode for the whole invoice (5 invoice date, 29 delivery date, or 72 payment date) and apply it to every tax breakdown entry; or remove the element if the country CIUS allows it.
