Inserting Application Components 
Logically speaking, an application component represents a participant of a Business Scenario. An application component is described by the following properties:
· By the role that it has within the Business Scenario (for example, supplier, plant)
· By the product that the application component implements (for example, SAP R/3 4.6C)
You can assign a Business Scenario both an application component and a role. You must specify the implementing product for the application component, including its enhanced name if applicable. Furthermore, you define the name of the WSCI interface for the application component.
You have opened a Business Scenario.

1. Position the cursor on an empty space in the Business Scenario. Call the function Insert Application Component from the context menu.
2. The systems displays the Insert Application Component dialog.
You have the option of defining the product that implements the application component. You can do either of the following:
¡ Choose a product defined in the System Landscape Directory
¡ Choose the product template option if the product is not defined in the System Landscape Directory
For more information, see Modeling Application Components.
3. Choose an option by selecting one of the radio buttons in the Application Component frame.
¡
If you require a product from the System
Landscape Directory, call the search help for the Product field and
select a product from the list. To do so, choose the search help icon (
).
The product you select is then copied to the Product field. Furthermore, all software component versions that are assigned to this product are displayed.

You can only select a product if at least one software component version has already been imported for it. If this is not the case, the system displays a corresponding error message. See the Handling Messages section.
For more information, see the Modeling Application Components section of this documentation.
¡ If you select to use a product template, the system enters Template in the Product field.
4. Specify an enhanced name (optional).
The enhanced name can be used to do the following:
¡ Specify the function area of a product in more detail.

For example, you could specify the enhanced name SAP FIN for an application component with the product SAP R/3 4.6C. This would indicate that this Business Scenario is relevant for the sub area Financials.
¡ Specify the product name, if it is a product template.
5. Enter the role of the application component (optional).
6. Specify a name for the WSCI interface (optional).
7. Confirm your specifications by choosing OK.
The system inserts an application component as a colored column in the graphical work area of the Business Scenario editor. The column header displays the role, the product (including release), and the enhanced name.
