LEAVE ACCRUAL RECORDS. Vacation and sick leaves are accrued based on the leave accrual codes established on the Payroll Personnel System (PPS). Leave code is established by the department when an appointment is initially set up. For staff employees thereafter, the PPS will re-derive the leave code on the appointment during month-begin periodic maintenance.
