– <Higher-level periods> To-Date
– Prior <Higher-level periods> To-Date
– <Higher-level periods> To-Date Change (automatically calculated categories)
– <Higher-level periods> To-Date Growth (automatically calculated categories)
The periods depend on the date levels defined in your model.
In the Cognos Transformer Categories diagram, relative time periods appear in the
category viewer as special categories, highlighted in pale green, below the other
drill-down paths in the time dimension. Grouped special categories only appear in
reports when the time dimension contains one or more levels higher than the
current period.
Set the Current Period Automatically
Although the current period is set automatically, you should explicitly select the
column to use from the Data Sources list.
If two or more data sources contain columns that provide date values, you will
avoid ambiguity by explicitly clearing the Sets the current period check box in the
other Data Source property sheets.
Procedure
1. In the Data Sources list, successively open the property sheet for each data
source containing a date column for the time dimension.
