BeX Reporting on BPC Cube

Hi Guys,

I am on BPC 7.5 service pack 7.

While creating application I see one option to select

"Enable SAP BusinessObjects Process Control Integration".

When this is used. I have noticed one thing that when I select this option I see one additional cube in the BI side named PLANNING_B. Is it basically to enable the BEX reporting?

If yes, than my question is cant we do bex reporting reporting on BPC mutiprovider or BPC Cube. What is the use of additional cube PLANNING_B.

Thanks
