In order for employee accrual balances to be properly flow between the HRIS and payroll application, the Leave Type name in the HRIS needs to match the Accrual Code in the Payroll system.
If the payroll system has an Accrual code configured to read "Sick," the leave type in HRIS needs to be called "Sick" as well. Any variation in spelling could lead to a sync issue.
When installing the sync for a client, it may be necessary to load accrual balances from the payroll provider. Once leave types are configured properly to sync, accrual balances can be loaded from the Utilities: Load Employee Data from Payroll. It is not necessary to run a load utility if the HRIS is the accrual engine.
