Is this a once a day report or something that will be run several times a day? The Reporter Pro level license will give you the best tools. It's also the most expensive. Service Level Summary is a good report for running over and over during the day. Set the filter ACD Hunt Group tab to the chosen queue. Set the report date and to the last 15 minutes. If you have an AutoReporter license (which I highly suggest), you can set this report to run every 15 minutes and be emailed, exported in Excel or post to an intranet page. If this is a daily report, use the Service Level by Half Hour. The report defaults to half hour increments. Use the same filter.

If you plan any changes to the report, do yourself a favor and make a duplicate copy first. Make your changes to the copy.
