Dynamic filter on measure based on prompt

Dear Community,

I´m trying to filter a measure based on the prompt. The user is able to select an intervall for the time period (e.g. January 2015 - September 2015) in prompt. In the Report the user shall see the months 01-09 for one measure but also see the month 09 for the second measure.

But the user also should be able to select another Intervall of month (e.g. 01.2015-08.2015) then the second measure should be for 08.2015.

Is there a specific function which I can use?

Thanks and kind regards,

Ann-Christin
