Designing a State Model

A state model is a set of states, events, and transitions. Transition is the transformation of a business object from one state to another. Events trigger the transition of a business object from one state to the next state.

2. Click on the States tab to create states. Refer to Creating a State, for the procedure to create states.
3. Click the Transitions tab to define transitions between states, and select on the tool bar. The Transition - Enter Transition Details window appears.
4. Specify the state from which the transition starts in the From State drop-down list.
5. Specify the state where the transition ends in the To State drop-down list.
