The My Totals view is a very powerful feature where the application can present any kind of summary of the planned or worked hours.
See the work history setup in the staff management to prepare what information is going to be displayed.
Note: There is an additional field Show on Portal which must be assigned in this setup to activate if the summary will be displayed on the employee portal. If not assigned then this summary would only be viewable within the staff management module (backoffice), but not on the employee portal.
