When validating an XRechnung created by odoo 16 (Odoo 16.0-20240522 (Community Edition)), I received the following (slightly misleading) message “Buyer electronic address MUST be provided (val-sch.2.1; PEPPOL-EN16931-RO-10)” After researching, this error message says that the customer's email address is missing. However, adding this does not change anything. I then found out that the customer does not have a VAT number. If I enter any number there, the validation is successful. Unfortunately, the validation also fails if I enter a “/” there, as suggested in the small help for the field.
What do I have to set in odoo so that valid XRechnung are created even if the customer does not have a VAT number?
