UN/CEFACT CII D16B vs. D22B

[gunnarvo]

Hi,
I can see that this conversion to UBL is based on D16B and not D22B. As far as I have understood, D16B is not fully aligned with EN 16931. Are the differences significant? Does this conversion properly handle i.e. ZUGFeRD v. 2.3.2 in most cases?

Best Regards

The EN 16931:2017 explicitly states to use D16B. The choice of´Zugferd to use D22B is their choice but not in line with the international standard. They claim that D22B is backwards compatible with D16B- it's their decision. The outcome of the mapping is tested against the Schematron rules of the EC and not against specific Zugferd rules.
