Step 1
From the side menu select Configuration, and then go to Leave configuration tile. From the drop-down list select Leave requests.
Step 2
In the Leave requests tab, find the item Calculate the number of days and hours based on the work schedule.
If you want the number of days and hours in the request to be calculated based on the working time schedule, move the slider visible on the right. If this option is not enabled, these values will be taken from the days off calendar and employee account details.
