Subject Area
Subject Area controls the measures and the attributes that you access when you create or view reports.
The default subject area includes all data in a space. A space administrator can create custom subject areas, assign those subject areas to space groups, and organize or rename items to support report creation in Designer and Visualizer.
All subject areas are automatically available in KPI Builder, and they dynamically update during report creation. Subject areas highlight relevant attributes and measures and hide items that are not available.
You can combine subject areas with column-level security to restrict data access.
Note that objects saved in an imported custom subject area are not available to users unless they are added in the parent space from which the subject area was created.
