Customer exit Variable to split single date value into a range

Question

Hi All,
we have a requirment where user will enter a date(01/21/2010) value in the variable input screen, it should be single value and mandatory, and the query output should have data for the Preceding 24 months for all 6 Key figures.  (e.g. user chooses 12/15/2009, result set is 12/01/2007 - to - 11/30/2009) summarized by month,
Our query design is as given below -
since we only have DATE value in the cube, we have added FISCAL YEAR/PERIOD in the cube and mapped DATE with time chars. Now the cube has the data stored in monthly buckets using FISCAL YEAR/PERIOD . Now we have used the variables  FISCAL YEAR/PERIOD  to restrict Key figures and have an offset on that to get the prior 24 periods.
Since in our requirement user wants to enter Date variable asmandatory input, we create 1 customer exit variables as a mandatory & single value variable for Date Variable, and using that exit variable we thought of passing the period of user entered date to FISCAL YEAR/PERIOD  which we are using to restrict Key figures and get offset of 24 months.
Can someone please help us in passing this period vaule from inout Variable Date to Fiscal year/period using CMOD, any other ideas are also welcome
Thanks in advance

Hi sateesh,
we are using DATE_TO_PERIOD_CONVERT ,but in this case if user enter's a date (01/21/2010) then we are getting output only for that date and not for the entire prior 24 months period
As per our requirment when user enter's date (01/21/2010) it should get the whole range that is entered date and 24 prior months and pass the range back to same input Variable so that in the output we get the data for entire prior 24 months
Thanks
