ZUGFeRD Validator fails with ZUGFeRD 2.3 and embbeded XRechnung

[hendriksander]

Hi,

we use the ZUGFeRD mustangproject to validate incoming ZUGFeRD invoices. We have encountered some issues with the ZUGFeRD 2.3 version in combination with embbeded XRechnung. For functional testing of our implementation we used the ZUGFeRD XRechnung files provided by the FeRD. We tested it with the version from the FeRD website (www.ferd-net.de/ZUGFeRD-Download) and also with the corrected version www.awv-net.de/upload/ferd/ZF23_DE.zip which was later provided by a Newsletter after the initial release of ZUGFeRD 2.3.

In the corrected version this ZUGFeRD with embedded XRechnung was provided. XRECHNUNG_Einfach.pdf

The ZUGFeRD validation report results of this file are the following:
zugferd-validierungsreport (33).txt

So it seems that the files provided by FeRD could not be validated correctly by the mustangproject or are corrupted. Can you confirm this?

Because it might be good to know we use the following code to get the ZUGFeRD profile and ZUGFeRD core-2.14.1:

public String getZUGFeRDProfil() { String guideline = this.extractString("//*[local-name() = 'GuidelineSpecifiedDocumentContextParameter']//*[local-name() = 'ID']"); if (guideline.contains("xrechnung")) { return "XRECHNUNG"; } else { switch (guideline) { case "urn:cen.eu:en16931:2017": case "urn:ferd:CrossIndustryDocument:invoice:1p0:comfort": return "COMFORT"; case "urn:cen.eu:en16931:2017#compliant#urn:factur-x.eu:1p0:basic": case "urn:ferd:CrossIndustryDocument:invoice:1p0:basic": return "BASIC"; case "urn:factur-x.eu:1p0:basicwl": return "BASIC WL"; case "urn:factur-x.eu:1p0:minimum": return "MINIMUM"; case "urn:ferd:CrossIndustryDocument:invoice:1p0:extended": case "urn:cen.eu:en16931:2017#conformant#urn:factur-x.eu:1p0:extended": return "EXTENDED"; default: return ""; } } }

Thanks for your help in advance.

Issue stems from the version-entry in FeRDs reference files. In profile XRECHNUNG the field value of "Version" is "3.0" which mustang validates to false:

mustangproject/validator/src/main/java/org/mustangproject/validator/PDFValidator.java

Line 242 in 2a00af8

final String[] valueArray = {"1.0", "2p0", "1.2", "2.0", "2.1"}; //1.2, 2.0 and 2.1 are for xrechnung 1.2, 2p0 can be ZF 2.0, 2.1, 2.1.1

We face the same issue at the moment. FeRDs document "1. FACTUR-X 1.0.07 DE.pdf" states that 2p1 should be the valid version code for profile XRECHNUNG (chapter 7.7) but the reference data tells a different story. It seems as if the XRechnung version is embedded instead of the ZUGFeRD Versions: "1.2", "2.0", "2.1". Following that logic "3.0" should be a valid value as well since 3.0 of XRechnung is released .

Is there an official version code list somewhere? Can anybody produce official documentation on the versioning of ZUGFeRD/Factur-X?

The official XRechnung specification can be viewed at https://xeinkauf.de/xrechnung/versionen-und-bundles/. Since XRechnung 3.0.0 the version number is 3.0.

The information can be found on page II in the document Specification Standard XRechnung.
