To create SV-4, make sure there are OV-5 and SV-1 created in the architecture.

The SV-4 view consists of two diagrams:

1. Functionality Description diagram. This diagram represents Functionality Description hierarchies.
2. Functionality Description Flow diagram. This diagram represents Functionality Description flows.

Before creating the Functionality Description Flow diagram, the Functionality Description diagram must be created first.

To create a SV-4 Functionality Description Flow diagram

1. Either create Function Actions or drag the Functions from the Containment tree directly to the diagram.
2. Connect the Function Actions using the Function Edges.
3. Display the possible Resource Exchanges on every Function Edge.

To display possible Resource Exchanges on selected Activity Edge, click smart manipulator named “Resource Exchange” that appears when Function Edge is selected. You will be able to select possible to realize Resource Exchange. Another way to invoke the Resource Exchange selection Dialog is to click on the “Resource Exchange” button in the Diagram toolbar and to click on the Function Edge.
