When activating the paid leave counter feature, it's possible the counters do not match the information you have perfectly, especially if you started your schedules during the period or your employees have additional days !
Head to the HR tab > Paid leave configuration
Select your location and your team, then click on "Modify counters" :
Edit as required the "Acquisition period N-1" column
Edit as required the "Acquisition period N" column
Don't forget to save !
Good to know : The paid leave counter is linked to the active contract. If your employee has changed contracts and the previous balance is to be retained, make sure you change the balance !
