I am confused, let me ask some questions:
1) When you start, are the 3 tabs (1,2 and 3) already displayed?
2) Do you want to replace tab 3 with the data from the View?
If so, then you want to have your process close tab 3 then open a new tab.
However, you have limited choices in a proces re: the output options.(see my post re: why buttons can do more than a process).
