Recently, several attendance activities can be crossed in GIRITON. For example, if you have Sickday on Fridays, you can also chose Homeoffice on the same day. Both activities are included in the calculations, ie. counted as 8 hours Sickday, and 4 hours Homeoffice.
To enable cross-activity support, in the In the “User - Attendance - Attendance activities” menu choose the activity Sickday and then the “3 Others” tab. Click on “It can run concurrently with other activities”.
