System component 
The Choices button opens a popup window to show available choices for the system component. Select one from the Choices window shown below, and click "Select", and it automatically fills in the system component field. If the system component you want is not in the Choices window, close the Choices window, click "New" on the Add System Component Instance screen, and it brings up the Add System Component screen shown below. Fill in the information for the system component (see the Add System tutorial page for what to put in each field), and click "Save". You'll be returned to the Add System Component Instance screen, with the system component field automatically filled in. If you then want to look in the Choices window again, click "Refresh" in the Choices window to make the new system component show up as one of the choices.


Not yet mapped
The new system component instance is NOT automatically mapped to DEAR domains (SRM, TRM, etc.) To map it, go back to the main screen, select the new system, and click on "Edit".
Where you go next
"Save" and "Cancel" will both take you back to the main screen.
