Hi Vamsi,
As the previous posters have stated, you will need to control the amount of quota transferred to the employee in each period using the PCR. You can set the base entitlement used in your selection rule in configuration to 1 day (8-hours). In each period you can define the number of hours/days that will be accrued by passing a value such as 2 or 3 to your time type which triggers the quota accrual. Since the time type used in your selection rule is a multiplier the amount passed to this time type in the PCR will be multiplied by the amount you define in the base entitlement (e.g. 2 x 8 = 16 hours accrued).
Hope this helps.
Regards,
Kory
