Detailed Reports produce more details than the Quicklist, and are configured by your administrator. Typically, this report will give you access to view most fields within a issue. Selecting Run Detailed Report and pressing the Go button will generate a report using the filters selected on the screen in the Query Filter section. Like Quicklist Reports, Detailed Reports typically also give you the ability to click into edit mode to edit the issue, assuming you have permission. They may also have other buttons to access issue history, or to delete the issue.
