Not expressible through the normbill invoice model — documented for completeness

How to fix it

Remove either cbc:TaxPointDate or the date-code qualified cbc:DescriptionCode from the document.

BR-CO-03 auf Deutsch — was bedeutet der Fehler?

So beheben Sie den Fehler

Entfernen Sie entweder cbc:TaxPointDate oder den Datums-Code aus dem Dokument.
