Add nationality codes in accordance with the standard
The country codes entered in the address picklist do not always correspond to the mandatory "ISO 3166-1 Alpha-2" standard for the e-invoice (XML file). Example: For Germany, the ISO code is DE (not D, D- or DE-). The "ISO country code (Alpha-2)" mapping ensures that the different notations of the country codes in the address are translated into the correct standard.
Go to the Configurations tab in the function bar and click on Mappings > ISO country code (Alpha-2).
Add more country codes as needed.
Enter the various notations of your country codes in the column From .
Enter the appropriate "ISO 3166-1 Alpha-2 Code" in the column To . Examples: From To FR- FR F- FR IT- IT I- IT Note: You can find the codes at https://www.laenderdaten.info/laendercodes.php
Save and close the mapping
