Divide months in separate rows for each dimension when Multiple months selected in Prompt

Hi Experts,

I have a requirement for a Summary report. I have a Dimension Field of Region and Reporting Period and all other columns having the fact data. If the user selects the multiple month for a for a report in prompt, then the Reporting period should show the separate month splitted in rows for each Region and as well the fact numbers split in each row too.

For Eg,

This is the Current Situation: If we select Prompt from: 01/2015 - 02/2015

Region         Reporting Period            Fact1            Fact2

North            012015                        2000              1000

South           012015                        1000               1500

East             012015                         3000              2000

But we want to make it as

Region        Reporting Period            Fact1            Fact2

North            012015                        1000              700

North            022015                        1000              300

South           012015                         400                700

South           022015                         600                800

East             012015                         1800              1100

East             022015                         1200               900

Any Idea would be appreciated. We have a hierarchy set up in the region level From Region-Sector-Unit-Worker level. So each time we drill down, this should reflect on each level.

Thank you,
