Anyone with a full license can access the Reports tab within the PPM environment. Note that if you have a Timesheet Only license, you can still access published reports from the IS&T Project Reports page.
After logging into PPM, click on the Reports tab along the top of the browser window. If you don't see a tab entitled Reports, please click on the See All tab and select Reports from there.
You will be taken to the Reports page which lists all publically available reports and folders.
