This activity is used to define a case task template. You can use a task template to group a set of activities. The task activities defined in the template are added as case tasks to the case when a particular template is selected. A case task template can be connected to a case category so that when a category is selected for a particular case, the task activities attached to that template are automatically attached to the case.
Task activities must have been defined on the Case Task Basic Data/Task Activity.
