This article explains some additional attendance settings in Runtime HRMS.
To access these settings, go to Setup > Attendance > Other Settings.
Here is an explanation of each item on this page:
Select from Present or Absent. This means that if there is no attendance information available for an employee on a date, what should be the default attendance to mark. If you select 'Present' all days where no attendance information is captured will be marked as 'Present'. This does not overwrite Holidays and Weekly Offs.
Present if Punch Found
If checked, this setting will mark Present if there is at least one attendance punch in the time data for an employee. Thus, even if you have not marked Present/Absent specifically, employee will be considered Present if he/she has a time punch on a day. This also does not overwrite Holidays and Weekly Offs.
Disallow Sand-witch Holidays and Weekly Offs
Selecting this option allows you to disallow holidays and weekly offs if an employee is absent on either a day before or day after the holiday or weekly off.
