Summarize
The Summarize action eliminates descendants, but rolls up their values for
representation in the selected category. The Cognos Transformer diagram shows
categories. Report users can drill down only to the summarized category. They
cannot see any of the category descendants.
You can apply the Summarize action in a dimension view and a custom view.
You cannot summarize special categories.
Category Inclusion Settings
To prevent cubes from showing zero values for categories that lack data, you can
specify that categories be included in a cube only if they occur in the data source.
Cubes that are more compact build faster and help report users to more quickly
focus on the relevant data.
The Inclusion setting is available in the Level property sheet, Category property
sheet, Drill Category property sheet and Special Category property sheet. If
specified on a category property sheet, the Inclusion setting affects only the one
selected category.
You can specify a default Inclusion setting for all categories in a level by
specifying the Inclusion setting on the Level property sheet. The setting then
applies to all categories subsequently created in that level.
The following table lists the available Inclusion settings and provides a description
of each.
Tip: You may not see all the settings listed in Cognos Transformer. The settings
that are available depend on the item you selected (level, category, drill category,
or special category).
Inclusion setting Description
Default (From Level)
Uses the setting for the level in which the category
resides.
Always include
Retains the category in the model and includes it in
cubes even if it, or any of its descendants, fails to
appear in the data source.The category is also
included if any of its descendants are included and
if the category is not explicitly excluded,
summarized, or cloaked in a dimension view. If
necessary, Cognos Transformer includes ancestors
of the category, regardless of their
Inclusion
settings. This is the default setting when you create
a time dimension. If you exclude time categories,
special categories that use relative time functions,
such as
Last Month
, will not work properly.
Suppress blank categories
(levels
only)
Retains categories in the model, but excludes from
cubes those categories with a blank source value.
