When adding leave or sickness you will receive the error message 'Can not determine absence period, please check dates are in range' if the dates on the absence are not within the date range of the absence period selected.
This could be caused by one of the below:
The absence period scheme not being set up correctly
The absence spans over several payroll periods
Absence period scheme
If the absence period scheme looks incorrect, you can change the dates by following the steps in our article on creating and changing absence period schemes.
If the employee should be on a different scheme, follow our guide on assigning an absence period scheme in order to change it.
Absence spans over several payroll periods
When adding sickness for an employee you will receive the error 'Cannot add/edit absence as it spans over a payroll period' when the sickness spans over two payroll periods.
To resolve this, you can either add two separate sicknesses and mark one as a continuation from the other or you can amend the Global Settings to allow for absence to span over several payroll periods.
For guidance on how to complete either of the options above, please follow the steps in our article on adding long term sickness.
