Hierarchies

Hierarchies are used to define a set of automatic data aggregations. There are two types of hierarchies allowed in a dimension: parent-child hierarchies and attribute-driven hierarchies. Parent-child hierarchies are based on a set of hierarchical relationships between parent and child elements. Attribute-driven hierarchies are hierarchies whose aggregated elements are derived from values stored in the attribute tables of the dimension.

On the Hierarchies tab, you can manage the hierarchies of the selected dimension. The tab shows a list of defined hierarchies. For each hierarchy, the name, description, default member, and hierarchy type are listed. Users can create, edit, or delete hierarchies and also set the default hierarchy for a dimension. Each dimension has a default hierarchy, which cannot be deleted.
