If your report has filters with Ask? turned on, you will see a screen that says “Update runtime criteria.”

This is where you will specify the values for which you’d like the query to search. Enter your operator and criteria. Checking the View All box will cause this filter to be ignored. When you’re ready, click the Update button to continue. If there are more filters marked Ask? you will be presented with another screen for the next filter. Finally, you will see a screen that summarizes the filers. Click Proceed to query to continue.

The report will run and it will appear in the output that you selected.
