Project Reports (also referred to as Project Summary reports) are run and viewed from a work item's Summary page. They are designed to output information related to the work item, such as schedule, Team Members, and Metric data.
The specific data exposed by these reports is based on templates that are uploaded as .jrxml files to the Report Assets page.
Note: Users require the "View Project Reports" Project Task permission on a work item to see its "Project Reports" module.
