If you have manually advanced the system calendar in the back office, for example when setting up a new annual leave year, you may find that absences can no longer be input and an error is shown.
⚠️Important: Manually advancing the calendar can cause it to fall out of sync with the payroll Current Period. This stops absences from being input correctly until the Current Period is updated to match.
Resync the Current Period
Go to System Params.
Click Ref A-C, then click Control Parameters.
Select the company.
Update the Current Period to the correct period.
Click Save.
Avoid this in future
When moving to a new annual leave year, use Portal to change the calendar rather than advancing it manually in the back office. This keeps the calendar and the payroll Current Period in sync and prevents this error.
