Omit Categories Using Cloak - IBM Cognos User Manual

For example, suppose that your company maintains branches throughout the
world. Some branches are identified by their country or region. Others are
identified by city only.
In your model, you structure the Regions dimension to show levels for Retailer
country or region and City. To streamline your cube, you suppress categories with
no associated source data.
In the resulting report, your users can drill directly down to subordinate categories
that reflect the current structure of your organization.
You can suppress both existing and blank categories in a level by suppressing the
level itself. However, to properly support the calculation of relative time categories
for the cube, you cannot suppress or exclude weekend days (Saturdays and
Sundays) and their associated measure values.
You can also suppress categories in different alternate drill-down paths, but you
cannot suppress more than one entire alternate drill-down path. Suppressing any
category located above the convergence level in a drill-down path has no effect on
categories in other drill-down paths.
Procedure
1. Open the Categories diagram for the dimension that contains the categories or
level to be suppressed and, if you have not already done so, add a dimension
view.
For more information, see "Create a Dimension View" on page 133.
2. In the Dimension pane, select your new view.
3. In the category viewer, select the categories or level to be suppressed and, from
the Diagram menu, click Suppress.
4. Open the PowerCube property sheet and click the Dimensions tab.
5. In the Dimensions list, right-click the dimension in which you created the
dimension view and click View.
6. In the Select a View dialog box, select the dimension view that you created,
and click OK twice.

Omit Categories Using Cloak

In certain situations, you may want to omit one or more categories with the
descendants of those categories, while retaining their values for rollup into
higher-level categories.
