Define A Scenario Dimension And A Cube Opening Level - IBM Cognos User Manual

Because the category values at the convergence level and below are shared by all
drill-down paths, removing or changing a category in one path at or below the
convergence level immediately affects the same category in all other drill-down
paths.
Procedure
1. In the Dimension Map, select the level that is to be the convergence level for
2. If appropriate, add intermediate (manual) levels to the new drill-down path.
3. To ensure you have not introduced uniqueness problems, from the Tools menu,

Define a Scenario Dimension and a Cube Opening Level

Scenario dimensions are often used when budgeting and forecasting, or creating
PowerCubes for planning-related applications.
Although scenario dimensions are not a distinct dimension type, you can flag any
dimension other than the time dimension so that its data never rolls up to either
the root category or a designated parent category, which remains hidden.
You first designate a level that is a child of the non-selectable upper level in your
scenario dimension as your new default opening level. You then set the Hide the
value option for the root or parent category, to ensure that values shown at your
chosen default level never roll up to this higher level.
We recommend that you always set a default opening level for your PowerCubes.
You thereby ensure that cubes containing budget values or other scenario-like data
do not display zeros, N/A, or meaningless numbers when opened by your report
users.
When you specify a default category that is not visible to some users because of
their security profile, the default category actually shown is the highest one in the
hierarchy that the users are authorized to see. The default view for those users will
show na for all measures if the default category has the Hide the value option
enabled.

Drill-Down. Alternatively, drag a column to the Dimension Map, as shown in
the following image.
Note: For a level to be a convergence level, it must be designated Unique on
its property sheet and the category values in the level must have unique and
unambiguous source values.
