If you use the Time Tracking and Time Off modules, you can configure which absences (conference, business trip, etc.) allow employees to still use the Clock-In feature during their absence period.
This feature is very helpful when using absence requests for "Home Office." When an employee receives approval for remote work, they are, of course, working and therefore need to use the Clock-In/Out function.
The new parameter can be found in the editing section of the leave or absence type.
