In the field 'Advance Notice' you can specify the number of days to indicate how many days in advance this leave type can be taken. For example, if you specify 10 days for vacations, any vacation request can only be booked 10 days in advance. However, when a leave request is booked by an admin, this setting is overridden, allowing the admin to book leave on behalf of an employee at any time
