None - aggregations only (scope definition)
When the scope definition of the box type is set to none (aggregations only), the box scope can’t be defined (it doesn’t exist in the box configuration), as the scope is based strictly on all sub-boxes. You will not see any task in any of the modules because such scope type can only aggregate data - there is no need to add any tasks to the scope.
Boxes with none scope definition show the aggregated status and time-tracking reports in the Hierarchy mode of the Overview module.
The Scope definition tab is hidden (can't be accessed in Box configuration > Tasks).
A "Box type" contains the default settings applicable to multiple boxes (all boxes of a given type). Those settings are adjusted in Box type Administration. Boxes can be created with different types of scope - those settings determine how a box can be configured and what can be done when defining a scope.
Box configuration refers to the settings of a single, individual box. They are dependent on the "Box type" settings.
For example, you want to create a portfolio overview and group several project boxes in the Overview module. As your tasks are already included within the project boxes, there is no need to configure the scope. The portfolio structure will be reflected in the Overview module.
