Double-click in ALV grid should take to BSP application

Hi,

In the portals, in an application, R/3 ALV grid is displayed. On double clicking one of the entries in the list, corresponding transaction in R/3 is opened and the details are displayed. Now, instead of opening the transaction in R/3, Corresponding PCUI application has to be opened. Is it possible to do it Portals? Can you please tell me how this can be acheived?

Thanks & Regards

P.S:- I'm not sure whether this topic can be discussed in this forum. Since the functionality is required in Portals, I'm putting it here.
