Focusing Relational Data

You can limit the data in your report with filters or query parameters. The method you choose should depend on the capabilities of the data source, the performance requirements, the persistence of the dataset, and how complex you want the report to be.

In IBM® Cognos® Analytics - Reporting, summary and detail filters are best for list reports in the relational reporting style. Summary filters are applied to summaries and detail filters are applied to details. These filters remove rows and columns from your reports.

You can also use prompts, or prompt controls, to allow report users to provide input for the filter.
