The "Saved Object Reports" allows to filter Users, Resources and/or Objects with Bookings for a selected period and then create report "snapshot" for this period. Any further changes that are done to Bookings or Time Reports will not affect the saved report. For more details refer to the Saved Object Reports manual.
Click on this button to create Custom Fields that will be available in the Object Report Editor window in the Saved Object Reports.
For more info about the different Custom Field Widgets, please refer to the Custom Fields section in this manual
