A filter allows you to limit the kind of data you want retrieved for your report. For example, you may want to create a filter to limit your report to information for only a specific department, or a specific profit center, or a data range.
You can have one or many filters in a report query – when you run the report, Cognos returns only those records that agree with all filters.
