Hi,
Go to stms_path transaction code...
Create a TR group as mentioned in my earliler reply with target system as QAS and SBX.
once all done you need to just add a transport route (F6) it will show the a pencil mark using which draw the route from DEV to TR group created.
and assign the layer to be used on the route done. Activate and distribute the settings.
Make sure the changes are done in Client 000. Hope this solves you issue.
Please find attached image for your reference.
