Drill through actions link when deployed to Share point.

Hi,

We are migration all our SSRS reports from Native SSRS mode to  Share point integrated mode.

we noticed that many of the report has drill through action which are using some dynamic links since the sub reports are not in same folder.

here is the sample action :

="javascript:void(window.open('" & Globals!ReportServerUrl & "/Pages/ReportViewer.aspx?/Production/Itero+Case+History&rs:Command=Render&rc:parameters=false&CBCaseID=" & Fields!CBCaseID.Value & "','_blank'))"

Now how can i modify this link in the report when we deploy this RDL to share point. this link is not working it is saying that the link does not exist.

Can any help me in providing the right expression for Action.
