Ability to create reports that adhere to the Factur-X standard.

Factur-X is a Franco-German standard for hybrid e-invoice which is a fully readable invoice in a PDF A/3 format, containing all information useful for its treatment, especially in case of discrepancy or absence of automatic matching with orders and / or receptions, and a set of invoice data presented in an XML structured file conformant to EN16931 (syntax CII D16B), allowing invoice process automation. Factur-X is the same standard than ZUGFeRD 2.1.

The i-net Designer offers a dialog in the menu "Report > Factur-X Mapping" to map datasource fields to their Factur-X representatives in the report. Factur-X is set up using profiles. By selecting the profile required for an invoice there are several static fields as well as invoice positions that need to be filled out. PDF files will always be generated using Factur-X when at least one field was set in the Factur-X dialog.
