WAD RRI Settings question

Hi,

I need to implement RRI in WAD.Once I click on a characteristic value in a table row of webtemplate_1,I need to capture the value of that characteristic and call another template webtemplate_2 which is filtered based on the captured characteristic value.

In Bex queries it is staright forward like setting the sender and receiver and creating a varaibale in the receiver query which is populated using RRI processing type.

Can someone give the step by step procedure for implementing this in WAD.

Thanks
