Javascript Problem for Drill Down Action in SSRS Report when integrated to PPS 2010

Question

Hi all,
I have a SSRS report which is integrated to PPS 2010(Performance Point Services) and it is having a drill down action through Go to URL action(I wrote javascript:void(window.open('xxxxx')) to open drill down report in new window).
This report has 5 parameters and all are multiple valued. Drill down report is opening very well when I open the report form Report Manager for any number of parameters values selected. But when I integrate the same report is PPS and deployed to SharePoint
then it is working only for 23 parameter values selected in PPS filters. If I select more the 23 values in PPS filters then the drilldown report is not opening.
But it is working well in Chrome, I verified in IE and Mozilla, both browsers are having problem.
When I look at Error Console of Mozilla, it is showing a javascript error as "Error: uncaught exception: ReferenceError: window is not defined" but the same report is working well if I select less than 24 filter values.
Please provide me the solution
Thanks in advance

Hi Vasu,
The issue might occur due to the Microsoft security update MS11-100 which limits the maximum number of form keys, files, and JSON members to 1000 in an HTTP request. Here, I suggest that you modify the Web.config file of the SharePoint site as follows:
<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="10000" />
</appSettings>
If the SharePoint site uses the port 80, the web.config file of the SharePoint site is located in the C:\inetpub\wwwroot\wss\VirtualDirectories\80 folder.
Reference:
An ASP.NET request that has lots of form keys, files, or JSON payload members fails with an exception
If the issue persist, please check whether there are any related errors in the Reporting Services log file which is located in <Drive>:\Program Files\Microsoft SQL Server\MSRSXX.<Instance Name>\Reporting Services\LogFiles.
