1 - About

With presentation hierarchies, roll-up information is displayed in the Oracle BI Answers navigation pane, providing users with important contextual information.

Holds data values that are organized using both named levels and parent-child relationships. This column is displayed using a tree-like structure. Individual members are shown in an outline manner. Hierarchies allow you to drill deeper into the data, to view more detailed information.

Most importantly, users can create hierarchy-based queries using these objects.

Presentation hierarchies expose analytic functionality such as:

  • member selection Filtering on Hierarchical columns is done through Selection Steps,
  • custom member groups,
  • and asymmetric queries.

As with other Presentation layer objects, you can also:

  • provide localization information
  • and apply fine-grained access control to presentation hierarchies and levels.

When you sort items in a hierarchical column, you always sort within the parent. That is, children are never sorted outside of their parent. The children are displayed below the parent in the proper sort order; the parent is not sorted within its children.

The Offices Total parent is always displayed above its children:
