Hello ZATCA team,
As I understand it, when an invoice needs to be issued to a foreign customer (say based in Switzerland); the Other Buyer ID (BT-46) <cac:AccountingCustomerParty / cac:Party / cac:PartyIdentification / cbc:ID>.should be OTH and filled accordingly.
Now, for example, the official VAT Number for Switzerland is CHE-123.456.788 TVA. Since alphanumeric values are only expected under BT-46, should this value be sent as CHE123456788TVA?
We tried sending the OTH=CHE-123.456.788 TVA but received a 400.
