Problem in selecting a single record...

Question

Hello experts,
How can I modify my code below in selecting only one wrbtr from table ekbe? Also, what is wrbtr and how does it relate to a certain PO? is it the balance? the PO amount? Thanks guys and take care!
CONCATENATE t_pohistory-mat_doc t_pohistory-doc_year
                INTO bkpf-awkey.
          SELECT SINGLE * FROM bkpf
                WHERE awkey = bkpf-awkey.
*AVH - removed wrbtr from selection
          SELECT augdt augbl shkzg dmbtr FROM bsak
                INTO (bsak-augdt,bsak-augbl,bsak-shkzg,
                      bsak-dmbtr)
                WHERE bukrs = bkpf-bukrs
                  AND gjahr = bkpf-gjahr
                  AND belnr = bkpf-belnr.
*AVH
            if not bsak-augbl is initial.
              select belnr gjahr from bsak
               into (bsak-belnr, bsak-gjahr)
                where bukrs = bkpf-bukrs
                 and belnr = bkpf-belnr
                 and gjahr = bkpf-gjahr.
                select awkey from bkpf
                 into v_bkpf_aw
                 where bukrs = 'GLOB'
                   and belnr = bsak-belnr
                   and gjahr = bsak-gjahr.
                  w_len = strlen( v_bkpf_aw ).
                  w_off = w_len - 4.
                  v_awkey_1 = v_bkpf_aw+0(10).
                  v_awkey_2 = v_bkpf_aw+w_off(4).
                  select wrbtr from ekbe
                    into ekbe-wrbtr
                   where belnr = v_awkey_1
                     and gjahr = v_awkey_2.
*AVH - Changed all bsak-wrbtr to ekbe-wrbtr.
                    IF bsak-shkzg = 'H'.
                      bsak-dmbtr = - bsak-dmbtr.
                      ekbe-wrbtr = - ekbe-wrbtr.
                    ENDIF.
                    IF t_pohistory-currency <> 'PHP'.
                      IF bsak-augdt GT pa_augdt.
             IF bsak-augdt IN so_augdt.
            t_amount-tramt = t_amount-tramt + ekbe-wrbtr.
                      ENDIF.
                    ELSE.
                      IF bsak-augdt GT pa_augdt.
             IF bsak-augdt IN so_augdt.
             t_amount-tramt = t_amount-tramt + bsak-dmbtr.
                      ENDIF.
                    ENDIF.
                  endselect.
                endselect.
              endselect.
            endif.
          ENDSELECT.
        ENDIF.

Hi,
I think you want total for a PO.
Write this :
data : ZWRBTR type EKBE-WRBTR.
select SUM ( wrbtr )from ekbe  into ZWRBTR           where belnr = v_awkey_1 
and gjahr = v_awkey_2.
ZWRBTR   will be the total amount of a PO means sum of all line items.
As you are using BELNR(Number of Material Document) and year then you want only one record then I think you want total PO value. The above code will retrieve total PO value.
