hi
  Two add two internal tables data.  first we need to create third internal table with all the fields of first two internal tables.
later u move the two internal tables data to third internal table
by looping the internal table which have more records or depending on the requirement and move the corresponding fields of first internal table to the third internal table and use the read statement with condition based on primary key of first itab and get the corresponding data of 2table into 3table.
i am sending the sample code to u.
check it out. i think u will understand how to move.
select vbeln waerk netwr erdat audat kunnr
   into table it_vbeln
   from vbak
   where vbeln in s_vbeln
     and erdat in s_erdat.
  if not it_vbeln[] is initial.
  select kunnr name1
   into table it_kunnr
   from  kna1
   for all entries in it_vbeln
     where kunnr = it_vbeln-kunnr.
  endif.
  loop at it_vbeln.
  clear it_final.
   it_final-vbeln = it_vbeln-vbeln.
   it_final-waerk = it_vbeln-waerk.
   it_final-netwr = it_vbeln-netwr.
   it_final-erdat = it_vbeln-erdat.
   it_final-audat = it_vbeln-audat.
  read table it_kunnr with key kunnr = it_vbeln-kunnr.
   it_final-name1 = it_kunnr-name1.
  append it_final.
  endloop.
