Defining default parameter values
To provide greater flexibility and power to an author, Cognos® Analytics - Reporting now includes the functionality to define default parameter values in a report. The values can be specified as a static text, a report expression, or a data item with a corresponding query.
Alternatively, you can use the preexisting Default selections property on certain prompt controls to provide static selections. However, applying default values for parameters is more powerful and flexible, and allows to provide dynamic default values.
To define default parameter values, use the new Parameters pane that is available from the Report menu.

In the Parameters pane, on the Default values tab, add an entry for each parameter that you would like to define default values for.

The list of parameters that was presented in the main Report pane in previous versions of Cognos Analytics - Reporting was moved to the Parameters pane, the All parameters tab. Using the links in the Set by column, you can easily navigate to the objects that are associated with the parameter.
