All the Intrastat functionality is available for all the EU countries as it is an European tax requirement. But the "Transfer" button on the top menu of the form which allows the user to bring all the EU trade transactions based on the criteria specified on the dialog window of the process, it isn't available for countries with no support by Microsoft on local requirements, such us Republic of Ireland or Portugal. As this process it's not a local requirement or country specific, it is just a easier and comfortable way to fill the Intrastat form (common functionality for all EU countries), companies from Republic of Ireland or Portugal should be able to use the functionality and the filter of the button should be changed as blank to allows every EU country.
