Multiple Rebate Agreements for single customer under same Time period

Hi All,

Our client requirement is to have multiple Rebate Agreements for each Customer namely, Quarterly Rebate, Half-Yearly Rebate and Annual Rebate.

Presently the Rebate Agreements are working correctly by deducting the Discounts already given in the individual Bills.

Similarly they need to deduct the Quarterly Rebate Value, while Settling the Half-Yearly Rebate, if the same falls under the specified time period.

For example if a Customer has Quarterly Agreement (from 01.04.2012 to 30.06.2012) and a Half-Yearly Agreement (from 01.04.2012 to 30.09.2012), while settling the Half-Yearly Rebate, system should deduct the Quarterly Rebate value, before calculating the Half-Yearly Rebate.

Similarly for Annual Rebate Agreement, system should first deduct the Quarterly Rebate value and then the Half-Yearly Rebate before calculating the Annual Rebate.

Please provide me the solution.

Thanks in advance.

Regards,
