How to post the consolidated accruals

Hi All,

I have the concern about the consolidating the accrual amount.

For instance I have an FD starting on 01/01/2012 maturing on 31/03/2012. The total interest is 300/-  which needs to be paid on the date of maturity.

I need to run the accruals on every month end. When I am executing the accruals for the month of JAN,FEB & March the system is posting accruals 100/-, 100/- and 100/- respectively./-.

But we have the requirement that  When I am executing the accruals for the month of JAN,FEB & March the system has to post the accruals 100/-, 200/- and 300/- respectively..

For the month of JAN, the accrual is 100/- i.e. Jan accruals

For the month of FEB, the accrual is  200/- i.e. Jan + Feb accruals

For the month of MAR, the accrual is 300/- i.e. Jan + Feb+March accruals

Please let me what sort of config nees to be done to get the consolidated amount for accruals!!!
