Hi,
<fs> type   t_data
sort t_data by matnr  month.
V_index = 0.
loop at  t_data  assigning <fs>.
V_index = sy-tabix + 1.
read  t_data assigning <fs2> with  index V_index .
if sy-subrc = 0.
--if <fs>-matnr =  <fs2>-matnr and <fs>-month = <fs2>-month.
<fs>-quantity =  <fs>-quantity =  <fs2>-quantity.
delete  t_data index V_index.
--endif.
endif.
endloop.
<b>then loop at  t_data to display .</b>
