ALV grid list report when selected from selection screen

Hi folks,

I need to get ALV grid display in my list report when selected the interval values from the selection screen. If I change the values in list of ALV grid it needs to be updated when I press UPDATE pushbutton. The output of list should be in ALV grid display.I need sorting ,flitering,totaling functionality in the list output.

For example if I selected BUKRS = 100 and 200 in the selection screen ,I need to display the ALV grid list in below the selection screen as ALV grid display...

Its urgent as I am new to ALV grid functionality...

Thanks in advance..
