I'm using an ALV tree grid to display a bunch of document headers and I'd like to add functionality when one such row is double clicked that a popup details window opens with additional data, preferably a grid like view of line items. Does anyone have input on how to use method handle_item_double_click to accommodate such a request?

Hi
In order to add additional buttons onto the ALVtree report the following sections of code need
implementing:
