Transport a released local ($tmp) transport

When you've released a local ($tmp) transport and still want to transport it across the system landscape, a transport of copies needs to be created.
Create, via SE01, a transport of copies as shown in the screengrab below

Select the transport of copies number and, via the menu, go to Request/Task --> Object List --> Include Objects (CTRL + F11)

A popup will appear in which you enter/select the local ($tmp) transport which has already been released (as shown in the screengrab below)

All objects contained in the released transport will be embedded in the transport of copies-transport which can be transported across the system landscape.
