After you create a worklet, add tasks by opening the worklet in the Worklet Designer. A worklet must contain a Start task. The Start task represents the beginning of a worklet. When you create a worklet, the Worklet Designer creates a Start task for you.
Create a non-reusable worklet in the Workflow Designer workspace.
Right-click the worklet and choose Open Worklet.
The Worklet Designer opens so you can add tasks in the worklet.
Add tasks in the worklet by using the Tasks toolbar or click Tasks > Create in the Worklet Designer.
