Authorized roles for actions on task templates
Access to the HumanTaskManager interface does not guarantee that the caller can perform all of the actions on a task template. The caller must be logged on to the client application with a role that is authorized to perform the action.
The following table shows the actions on a task template that a specific role can take.
