If you have not used PeopleForce before, and you do not have a history of previously taken vacations in the system, you need to balance them in employee cards.
To do this, go to the "Time Off" tab in the employee's card. You will see the "Adjust" button, which will allow you to subtract or add the required number of days to get the correct balance. For example, the employee has a balance of 11 days, but according to your data it should be 8 days). Click the "Adjust" button and subtract the required number of days.
After this adjustment, the balance will be drawn up, and further accruals will be made according to the rules that you configured earlier. Perform the same action for all employees in order to put down the correct balances.
