Creating Systems 
You create a system in order to connect to a specific back-end application or Web service.
There are three methods for creating a new system:
Use an existing template. For information, see Running the System Landscape Wizard.
Copy an existing system.
In the Portal Catalog, right-click the name of the system you want to copy and choose Copy.
Right-click the name of the folder to which you want to copy the system and choose <paste method>. For information about the two paste methods, see Copies and Delta Links.
Note
A system alias cannot be copied. If you create a new system through the copy/paste method, you need to define a new system alias for it. For information, see System Aliases.
Create and upload an XML file describing the system.
The creation of the XML script is generally performed by content developers. The file must then be uploaded to portal content, either by the developer or the system administrator. For more information, see XML Content and Actions.
