Defining a Task Flow Return Activity
When you define a task flow return activity, you need to specify the outcome that is returned to the calling task flow. You can have only one outcome per task flow return. The calling flow should have a control flow rule that corresponds to the outcome that you name in the task flow return activity.
The example in the slide shows the task flow that calls the shopping cart flow. The shopping cart flow has a return activity, depicted on the right side of the slide, whose outcome is defined as checkout. The calling task flow has a control flow rule named checkout, so when the called shopping cart flow is exited via the Checkout task flow return activity, navigation in the calling task flow proceeds to the CheckoutFlow.
