Resolving The Parentage Of Orphan Categories; Resolve Invalid Date Errors - IBM Cognos User Manual

It is possible for parents to add rollup values from some children and not from
others. If no child categories have Category rollup selected, then the parent
category becomes a placeholder and no values are associated with it when viewed
in the OLAP reporting component.
Note: You cannot perform rollup on the highest level of a special category.
The Category rollup check box appears for special calculated categories. However,
special calculated categories do not roll up to parent categories, even if this box is
selected.
Procedure
1. Open the Categories diagram for the dimension that contains the special
2. Open the property sheet for the lowest-level special category.
3. Click the General tab, clear the Category rollup check box and click OK.

Resolving the Parentage of Orphan Categories

When you generate categories from your data source or automatically generate
categories at cube creation time, Cognos Transformer reads and analyzes your
source data and builds category trees for the dimensions and levels in your model.
Any source data that cannot be placed into a drill-down path are put in Orphans
Of parent categories. By default, these categories, called source (or key)
orphanages, are suppressed.
To eliminate source-category orphans, we recommend that you either remove the
orphan categories from the source file or use drag and drop in the Categories
diagram to associate them with their proper parents.
For example, suppose your model contains two data sources. One is from an
order-tracking system, and supplies data for the Country, Region, Branch, and
Customer Number categories. The other contains Customer Number and Address
information. If the first source contains data for last year's orders and the second
contains customer records from the two preceding years, any customer number not
associated with an order in the period covered by the first source generates an
Orphans Of category. This Orphans Of category should be resolved before you
publish the PowerCube.

Resolve Invalid Date Errors

In most cases, Cognos Transformer can determine and apply the correct date
format for input from a source column.
An Invalid Dates category is automatically generated when the correct input
format cannot be determined or when a problem arises with the source data.
You may have to change the format of the date information in your source file,
change the Date input format property on the Time tab of the Column property
sheet or, if the data is corrupt, rebuild your source file.
Procedure
1. In the Data Sources list, open the property sheet for the column on which the
