Common filters for 2 objects from different App in Webpart

[#1]

Hi All,

I am using different objects from different QVW in qlikview sharepoint webpart. I want to use common filters for all objects

I am showing Employee data from Employee.QVW

Sales Data from Sales.QVW

like this...

Now there is one common field between these applications is employee Id. I put Employee Id as listbox. When this is selected it should filter data from both Employee as well as Sales Data.

How can do this on webpage

Thanks in Advance.
