We use the Entitlements Accruals screen in payroll to track our employee profit sharing program. It appears the program (not sure if it's Simply or Crystal Reports) DOUBLES the entered accrual amount - I entered "450" but on the pay stub it shows "500". The really weird thing is it only seems to print double the amount the first time - subsequent pay stubs show the correct accrual amount.
If it balances on the first try, you obviously made a mistake! :)
