When you use a worklet in a workflow, you can configure the same set of general task settings on the General tab as those that you configure for any other task. For example, you can make a worklet reusable, disable a worklet, configure the input link to the worklet, or fail the parent workflow based on the worklet.
In addition to general task settings, you can configure the following worklet properties:
Worklet variables.
Use worklet variables to reference values and record information. You use worklet variables the same way you use workflow variables. You can assign a workflow variable to a worklet variable to override its initial value.
Events.
To use the Event-Wait and Event-Raise tasks in the worklet, you must first declare an event in the worklet properties.
Metadata extension.
Extend the metadata stored in the repository by associating information with repository objects.
