Report Filters allow you to refine the results of a Report so that you can narrow down the data to what is relevant to you.
The Filters available will depend on the Report you are viewing and will appear above the Report results. An example of Filters is shown below for the Activity Completion Status Report (one of the pre-defined Reports available).
Some Filters allow you to simply enter data to be searched on, such as the User's Last name.
Other Filters allow you to select from a list of options, such as Completion Status - in the below example we can select Incomplete and Not Attempted so that we can Report only on people who are yet to complete their Activities.
If you change any Filters, click Run Report to run the Report again with the Filters applied.
