Unable to pass multi-valued parameter to sharepoint list dataset in my ssrs report

Hi Everyone,

I have done the below steps to retrive the result from the report when I am passing multiple values from one filter (multi-valued Parameter)

1. Create the report with sharepoint list as a datasource and report rendered properly when I am passing single value (In this case : I haven't selected Allow multiple values for my parameter)

2. Now I am trying to pass multiple values from my parameter to report

   i) selected the option "Allow multiple values" for my paramter

  ii) Provided the available values manually entered (3 values) and provided the default value (manually entered) and which are part of my sharepoint list values ( I have verified and Passed the same values in case 1)

 iii) Modified the main report dataset  in report data section by selecting filter option

Example: BusinessUnit is my parameter and the values are B1,B2,B3

       dataset name: BusDet (sharepoint list dataset)

        Open the dataset properties and selected the filter option and 

            Field = Business Unit  and  conditin is "IN" and value= Parameters!BusinessUnit.value

That means, Dataset is ready to handle the multiple parameter values.

But, I am geeting the error is " Cannot add multi value parameter 'Value' for dataset 'ReportData' because it is not supported by the data extension."

Please help me. 

Thanks in Advance.
