Example - Two Custom Views, Each With An Apex In The Same Dimension - IBM Cognos User Manual

A user can be a member of several user groups or roles, and can belong to
multiple custom views. In IBM Cognos, when a user belongs to more than one
group or role and the group, roles, or user belongs to multiple custom views, the
cube opens with a union of all the custom views.
A union of custom views combines the access capabilities of its member custom
views, but not their restrictions. The rules for determining what is shown in the
cube as a result of a union of custom views are
v that which is shown to an individual custom view is shown to the union
v a category is shown to the union if it is shown in at least one custom view
v measure values, or cell values, are shown to the union if there is at least one
v in a union of custom views, the root category shifts to the lowest common
These rules apply to all custom views in the union. The following examples
illustrate the union of custom views in different scenarios.
Example - Two Custom Views, Each with an Apex in the Same
Dimension
This example describes the union of two custom views that each have an apex in
the same Region dimension.
Custom view A: apex Australia
Custom view B: apex Tokyo
There is no visible common root for the two apexed categories. When the cube is
opened with the union, the lowest common ancestor of the apexes is shown: Asia
Pacific. In accordance with the roll-up rule, the rolled-up value at Asia Pacific will
be Australia and Tokyo.
Note: If the PowerCube has the Block totals for parents with excluded children
option set on the Processing tab of its property sheet, the value of Asia Pacific is
N/A.

That which is not shown to an individual custom view is the same as that which
is not shown to the union.
custom view that sees all the categories in the cell domain
A measure value, or cell value, is not shown to a union when none of the
custom views in the union can see all the categories in the cell domain.
