Printing Issue

Hi Guys,

I have a selection screen.

From the selection screen I have an ALV output.

On the ALV output I have added 2 more push buttons.

When I press 1st push button I get one output and if I press the 2nd push button I get another output.

My requirement is I need to put 2 check boxes in the initial selection screen(This I can make it).

When I select any one of the check boxes, any one of my push button should execute directly and print the output directly .

When I select both the check boxes,those two push button code should execute and should print the output directly.

How can I do this.Plz let me know.

Thanks in Advance.

Prasad.
