The Impact Analysis
function enables you to view the relationship of a cube to the objects
that it is associated with. Impact analysis shows the potential impact
of changes that you might make to a cube. In SAS OLAP Cube Studio,
you can perform impact analysis only on a cube. If a cube has an information
map, it is also displayed. The Reverse Impact Analysis function enables
you to see how changes to the cube's associated objects could affect
the cube. This view shows all tables that the cube is composed of,
including the input, detail, and aggregation tables. Impact Analysis
and Reverse Impact Analysis display only the objects for which you
have ReadMetadata permission.
To perform impact analysis
on a cube, select a cube in the tree view and select
Impact
Analysis from the
Tools menu
or from the cube's context menu. The Impact Analysis dialog box appears.
The dialog box contains the
Impact Analysis tab and the
Reverse Impact Analysis tab.
Each tab contains two options that enable you to toggle between a
tree view and a diagram view of the cube and its objects. The diagram
view shows a process flow diagram of the cube.
Each node of the cube
analysis also contains a context menu that is available on both the
Impact Analysis and
Reverse Impact Analysis tabs. This context menu enables you to see the object's properties,
analyze columns, and open (view the data in) a table. You can also
print the analysis view at any time.
Note: You can use SAS Data Integration
Studio to perform impact analysis on other objects, such as tables
and jobs. For further information about the use of the Impact Analysis
function in SAS Data Integration Studio, see "Using Impact Analysis"
in the
SAS Data Integration Studio: User's Guide.
