It may happen that employees are absent and that when you export the Absenteeism report, their absences are not present in the exported report.
To begin, you need to know that for an absence to appear in this report, you need to have left the time entry blank with the words Missing time entry, like this:
If you don't see certain absences in your report, check your employees' timesheets. It's highly likely that a time off of absence type has been added, rather than leaving the time entry blank.
If this is the case, don't panic: you can use another report to account for absences entered as Absence. Simply export the Time entries report on the Attendance category.
Be sure to select the date range of your choice, then under Options choose Only show time off then the leave type Absence (unpaid).
IMPORTANT: To avoid having to extract the information from two different places, we recommend that you standardize the way you record absences.
