Need to display two alv grids at one shot

Hi I need to display two alv grids at one shot.I need to use the FM:"REUSE_ALV_GRID_DISPLAY". Currently i am calling this function module twice and in output i am getting two ALV's in a overlapped manner.If i click on the back button then the first ALV is getting displayed.Is there any fisible solution to this?Is there any other function module that can be used

<b>Note please: I am not suppose to use OO ALV here.I mean splitter control will not help.List alv wil also not help.</b>
