Check the below code which i modified according to your data.
REPORT z_sample_alv.
data : begin of i_data occurs 0,
       f1 type c,
       f3 type c,
       f2 type i,
       end of i_data.
data wa_data like i_data.
data flag type c.
data v_f2 type i.
data v_f3 type i.
start-of-selection.
i_data-f1 = 'a'.
i_data-f2 = 2.
i_data-f3  = 'm'.
append i_data.
clear : i_data.
i_data-f1 = 'a'.
i_data-f2 = 3.
i_data-f3  = 'm'.
append i_data.
clear : i_data.
i_data-f1 = 'a'.
i_data-f2 = 1.
i_data-f3  = 's'.
append i_data.
clear : i_data.
i_data-f1 = 'b'.
i_data-f2 = 2.
i_data-f3  = 'p'.
append i_data.
clear : i_data.
i_data-f1 = 'b'.
i_data-f2 = 3.
i_data-f3  = 'p'.
append i_data.
clear : i_data.
i_data-f1 = 'b'.
i_data-f2 = 4.
i_data-f3  = 'r'.
append i_data.
clear : i_data.
sort i_data by f1 f3.
loop at i_data.
move i_data to wa_data.
at first.
write:/2 'f1', 22 'f2',35 'f3'.
endat.
v_f2 = v_f2 + i_data-f2.
v_f3 = v_f3 + i_data-f2.
at end of f3.
write:/2 wa_data-f1,13 v_f2,35 wa_data-f3.
clear v_f2.
endat.
at end of f1.
skip 1.
write:/2 'Sub total',13 v_f3.
skip 1.
clear v_f3.
endat.
clear : flag,
        wa_data,
        i_data.
endloop.
Thanks
