When a user creates a transport proposal in the transport workflow, he or she must only be able to use the direct target systems defined on the transport routes, and not all systems in the landscape.
To restrict the possible systems to direct target systems, proceed as follows:
The ON setting restricts the available systems to direct target systems. You can still delete systems from the available group of target systems.
If the setting is EXCLUSIVE, you cannot delete systems from the available group of target systems. This makes sure that all the specified transport requests are imported into all systems in the transport landscape.
In the Create Transport Proposal dialog box, you can only select the direct target systems on the transport routes as transport targets.
For more information on setting transport parameters, see Configuring the Transport Control Program tp.
