ALV list display

Hi friends,

I have implemented an ALV grid list using 'REUSE_ALV_GRID_DISPLAY' function module.It displays like this-

SO No Item PO date Advance Amt

31410 10 2006/05/01 500.00

31410 20 2006/05/02 500.00

31410 30 2006/05/05 500.00

31411 10 2006/05/01 100.00

31411 10 2006/05/06 100.00

I want to display advance amount once for each sale order ,bcoz it is at sale order level.I want to display it in a vertical column only and don't want to show it horizontally like sub total row....

Can some body help me out for achieving this functionality...

Thankin You

Regards,
