What this error means and how to fix it
An XRechnung rule (the German CIUS published by KoSIT, rule text in German): Germany requires more than EN 16931, for example the buyer reference / Leitweg-ID (BT-10), seller contact details (BG-6) and payment instructions. This is a warning: on its own it does not reject the invoice.
