Import

The XMLPort only imports data.

Export

The XMLPort only exports data.

Both (default)

The XMLPort can import and export data.

If the XMLPort uses a request page, as specified by the UseRequestPage Property, then an option appears on the request page that enables the users to choose to import or export data. Note: request pages show when the XMLport is run from Object Designer, and action page, or the Run function in C/AL code. Dooes not show with Export Import finctions

If the XMLPort does not use a request, then XMLPort defaults to Import, unless you specify the direction by Import parameter of the run function.
