Bi-Weekly schedules
Employees with a schedule with two different weeks cannot be read via Personio's API.
In case you have employees on such a schedule you will see them at everychange with the employee so also changes on a different field. There are 2 workarounds.
Workaround 1:
Decline the change from the concept mutation. With a change in the BI-weekly schedule it needs to be entered manual in eveHRyday.
Workaround 2:
Deactivate the attribute workschedules. You now will have to change anyworkschedule directly in eveHRyday.
