REUSE_ALV_GRID_DISPLAY

i cannot get your question properly but

if you are asking what value you have to pass in

it_sort-group then you can pass '' or 'UL' means it will group that as per your it_sort-fieldname. and '' means grouping comes on next page and 'UL' means under line comes after every grouping

U append the it_sort table with the firldname based on which you like to sort.
