Insert the following code into the PBO of the screen after the ALVtree has been created.

i.e after 'CALL METHOD gd_tree>set_table_for_first_display' has been executed.

Hi,

you should have local event handler method to respond the double click on item.

METHODS handle_item_double_click
      FOR EVENT item_double_click OF cl_gui_alv_tree
      IMPORTING node_key
                fieldname.

the above one should be implemented and then need to set the handler.

in the implementation get the order number and set the parameter id, and then call transaction TCODE skip initial screen ..
