STMS import of transport

Hi Guys,

I'm trying to import a transport during upgrade from dev to quality. I need to have it in 005 quality.

1) Is it necessary to login to the target client 005 or can I directly login to 000 and select target client 005 ?

2) Is it necessary to always import changes in all the clients ?

3) After clicked on the import icon (truck), I select (F4) to see available options for clients. When I do that, it asks me to login to the target client. What might be the problem ? Is some RFC destination configured incorrectly or some parameter ?
