The price plan window is a workspace where you create, set up, and modify a price plan.
The title bar displays the name of the window on the left and the Minimize, Maximize, and Close buttons on the right.
The components toolbar is available when you click the price plan icon 
in the tree display area. The toolbar contains shortcut buttons to calculation tools (called components) that are categorized into five families according to their main functions.
If you have not yet added a component to your rating tree, only the Rates family icon is available. After adding a Rate component, the other four component families are available, as shown below:
The rating tree display area shows a graphical representation of the rating tree, which is made up of rating components that appear as icons. By clicking on different elements in the rating tree, different information is displayed in the tab area, and different component families are available on the Components toolbar.
The identification area allows you to identify and describe the components which are included in a price plan. This area always contains two fields to type the name and the description of each component that you want to include in your price plan.
Depending on the selected component in the rating tree display area, the tabs display different fields to enter information. The above illustration shows the tabs that is displayed when a new price plan has been created and before adding components. At this point, the tabs include the following:
