Advanced Pricing Accrual Rebates

Hi All,

I am new in Advanced Pricing module so I need help to setup my two cases.

Case One

I have a process for giving rebate at the end of the third month. The rebate amount should be calculated as percentage of sell volume based on particular quantity. At the end of the first month the rebate accrual needs to be created. At the beginning of the next month the rebate accrual for the first month need to be reversed. The process repeats for the second month as well. At the end of the third month the rebate amount needs to be calculated for the quantity sell from the first to the third month.
