Transport logs only exist for released transport requests

What causes this issue?

You cannot display transport logs for the selected request.
Either no transport is allowed for the selected request type
or you have selected a task (tasks cannot be transported by themselves)
or the request was not assigned to a target system. Customizing
requests without an assigned target system are released locally, and
cannot be exported.
