Splitting interval values to different customer exit

Hi

i have a report in which i will pass the month interval in the variable, let say the values is 04.2004-08.2004, then in the final output i need to restrict the keyfigure withe corresponding month dividing like 04.2004,05.2004,06.2004,07.2004 and 08.2008 with 4 selection creating.

The no. of selection should change dynamically depening the no. of month in the interval.

Hope you got my question.
