The Factur-X export creates a standalone CII XML invoice for automated processing. The result is an XML file and does not contain a visual report.
Unlike a PDF export with Factur-X, the standalone export does not create a PDF/A-3 file and does not embed factur-x.xml in a PDF. For the general Factur-X standard, supported profiles, mapping, and validation, see Factur-X / ZUGFeRD.
A valid Factur-X mapping in the i-net Designer is required before exporting. The mapping assigns report and datasource fields to the invoice fields defined by the selected Factur-X profile.
Request the export with the URL parameter init=facturx. There is no format-specific export settings dialog for Factur-X.
