For self-invoice you need to use dummy Supplier and customer.


Please create dummy Supplier and dummy customer with same details of your Company (Do this one time activity for each company).
Then whenever you have Non-EU invoices for this company you have to create self-invoice for it, that is one supplier invoice (incoming self-invoice) and one customer invoice (outgoing self-invoice).
