How to pass parameter values in drill through reports?

Question

Hi All,

I am trying to give a link between two reports (back and forth), where both the RDLs are in same project.

Each reports are having 2 multivalued parameter where the second parameter is dependent to the first one(cascaded). How do i pass the multivalued parameter . i tried giving parameter1= join(Parameters!PI_REGION_LIST.Value,",") parameter2 =join(Parameters!PI_CENTER_CODE.Value,",")

when i click on the link , the second report is not running, it just shows the parameter pane where both these parameters as balnk.

same thing happening from the second report to the first.

How do i pass these multivalued parameter values, is that cascading parameters wont work in drill through .

Any help would be really appreciated

Thanks, San
