You must add Interactive activities within a role lane in the process. When you try to add an Interactive activity outside a role lane, Studio prompts you for an already existing role or allows you to create a new one.
The role lane where you add the Interactive activity determines which users can access it. Only the users assigned to that role can run the Interactive activity.
You must connect an Interactive activity to the process flow using an inbound and an outbound transition. An error appears in the Problems View if the inbound or outbound transitions are missing.
Some tasks may require you to define an argument mapping. For more information, see the corresponding task in Flow Object Tasks.
You can use an Interactive activity to handle a business exception. The activity that throws a user-defined exception is connected to the Interactive activity through an exception transition. For more details about exception handling, see Handling Exceptions.
