You may not want to install all the SAP Systems you have planned for your system landscape at the same time. However, you can use TMS to configure SAP Systems as virtual systems in the transport domain so that you can model the transport routes of your whole system landscape.
Most of the TMS display functions can be used for virtual systems.
To configure a virtual system:
The system overview appears.
The Evaluation: Configure Virtual System dialog box is displayed.
The domain controller is proposed as the communications system.
The communications system is required to act as a substitute for accessing the transport directory.
