PMO's (project administrators) have permissions to authorise any timesheet added to a project. They can do this in the projects module.
Authorising a timesheet as a PMO:
1. Go to Main Navigation > Projects
2. Click the Authorise Timesheeets tab
3. Scroll down to the Authorisation Time Filter and click Search
4. To bulk authorise all the timesheets that show, click the green Authorise button
5. To authorise a single timesheet, click the View icon next to it and then click Authorise
You can also filter the timesheets using the arrows next to each heading. You can filter by project, manager, number of users or number of timesheets.
