Reference

BR-11 Buyer country code is required

The Buyer postal address shall contain a Buyer country code (BT-55) identifying the buyer’s country.

This is an EN 16931 core rule. The buyer country is decisive for VAT treatment and the place of supply, for example to tell a domestic sale from an intra-community supply. A country written only in an address line does not count, and the code must be a valid ISO 3166-1 alpha-2 value (BR-CL-14). In CII, BT-55 is ram:BuyerTradeParty/ram:PostalTradeAddress/ram:CountryID.

Solution

Add cac:PostalAddress/cac:Country/cbc:IdentificationCode with an ISO 3166-1 alpha-2 code such as DE within the buyer address.
