Unable to pass multiple values in a multi-select parameter to a SSRS report(PPS Dashboard) in Sharepoint 2013 integrated mode

I have a SSRS report which gets values from SSAS cube, with more than 10 parameters defined in the report. All the parameters are multi-select parameters and the report works fine when deployed in sharepoint 2013.

I have integrated the SSRS report in PPS(Performance Point) dashboard and deployed in SP 2013. The dashboard contains Performance point filters and SSRS reports integrated together.

When I select multiple values for each parameter(PPS Filter), the report does not get executed and retains the previous page or renders a blank page.

Can you Please help me on how to pass multiple values from a PPS filter to SSRS report which has more than 10 parameters.
