The 'Favorites' tab is the default tab when 'My Reports' is loaded and lists all reports marked as a 'Favorite' in alphabetical order. If no reports have been marked as a 'Favorite', then the 'Favorites' tab will be empty.
To mark a report as a 'Favorite', navigate to one of the Report Category tabs and locate a report to add to the 'Favorites' tab. Click the star icon to the left of the report name to save the report to the 'Favorites' tab.
Reports can also be removed from the 'Favorites' tab by clicking the star icon next to the desired report.
