A filter sifts the data in your data source to bring back the information that answers exactly what you require. When you analyze a report, it is important to understand the filter conditions that are being applied to the report. This allows you to better understand what data is being excluded from the results.
You can see filter definitions and apply a filter in several ways:
Looking at the definition of a report's filter: To see the filtering conditions the report designer applied to the report see Viewing report filters.
Creating a View filter: If you have MicroStrategy OLAP Services, you can apply a filter to the current instance (or view) of a report using a View filter. The View filter limits the data being displayed on a report without re-executing the report against the data source. See Filtering displayed data: View filters.
Creating a report filter: If you are a report designer and want to know how to apply conditions to a report filter or create a stand-alone filter object, see Modifying report filters and creating filters.
Displaying or hiding rows and columns: You can narrow your view of a report to only the rows and columns you want to see. This is achieved using the Filter on Selections feature. See Displaying or hiding rows and columns: Filter on Selections.
