Configuring a Third-Party System 
Unlike SAP products, third-party products are not necessarily included in the component description. Therefore, you must first register the third-party product before you can register an installed application system of this product in the system landscape description.
This section describes how to do this task.
You require the user role LcrInstanceWriterLD to execute this task.
You have navigated to the Technical System Browser.

1. Choose New Technical System.
The browser displays the screen Technical System Wizard.
2. Choose Third-Party System, and then choose Next.
The browser displays all the registered product versions in the list Available Products.
3. Select the products that are installed in this system, and then choose Add.
The browser displays on the lower part of the screen a list of all the software components that are contained in the selected products.

Repeat this step as many times as necessary until you have added all products.
To remove a product, select it in the list, and then choose Remove.
You can add more products to this system at a later stage.
4. Select the software components that are actually installed in the system.
5. Choose Next to continue.
6. Enter the system name and the host name of the system, and then choose Finish.
The SLD server creates the new third-party system.
