When using the Jump to Report action int he web browser, the target report is displayed

in the same browser window by default. You can call the JavaScript window.open method

to open a new browser window. Use an expression to build a Jump to URL action with

the appropriate report server, folders, report name and parameter values. The script

to do this might look something like:

="JavaScript:void window.open('http://ReportServerName/ReportServer?/Sales Reports/Product

Sales Report&rc:Toolbar=False&ProductID=" & Fields!ProductID.Value & "', '_blank',

'toolbar=0',scrollbars=0,status=0,location=0,

menubar=0,resizeable=0,directories=0,width=600,height=500,left=550,top=550');"
