Workflows can contain reusable task instances and non-reusable tasks. Non-reusable tasks exist within a single workflow. Reusable tasks can be used in multiple workflows in the same folder.
You can create any task as non-reusable or reusable. Tasks you create in the Task Developer are reusable. Tasks you create in the Workflow Designer are non-reusable by default. However, you can edit the general properties of a task to promote it to a reusable task.
The Workflow Manager stores each reusable task separate from the workflows that use the task. You can view a list of reusable tasks in the Tasks node in the Navigator window. You can see a list of all reusable Session tasks in the Sessions node in the Navigator window.
