Loop not working in oo-alv method

Dear Friends,

I am working on oo-alv interactive report.

but the code in the method of double_click event is not working.

Actually i have the detailed data in it_final2.

IN the first secondary screen i have to display the detailed data of the selected line.

I attached my second fcat to the respective set_table_for.... but it is stil displaying the first fcat fields only.

can anyone help me.
