First and foremost, i would advice you not to use words like VERY URGENT in your subject. You might want to go through the following link to understand the basic rules of the forum:

For your requirement, below code might help you understand the logic in determining the link between BKPF and MKPF.
TYPES: BEGIN OF t_bkpf,
         bukrs type bukrs,
         belnr type belnr_d,
         gjahr TYPE gjahr,
         awtyp type awtyp,
         awkey type awkey,
        end of t_bkpf.
types: begin of t_mkpf,
         mblnr type mblnr,
         mjahr type mjahr,
       end of t_mkpf.
data: i_bkpf type STANDARD TABLE OF t_bkpf,
      i_mkpf type STANDARD TABLE OF t_mkpf.
data: wa_bkpf type t_bkpf,
      wa_mkpf type t_mkpf.
PARAMETERS: p_bukrs type bukrs OBLIGATORY,
            p_gjahr TYPE gjahr OBLIGATORY.
START-OF-SELECTION.
  SELECT bukrs belnr gjahr awtyp awkey
    into table i_bkpf
    from bkpf
    UP TO 20 ROWS
    where bukrs = p_bukrs
    and   gjahr = p_gjahr
    and   awtyp = 'MKPF'.
IF NOT i_bkpf[] is INITIAL.
   select mblnr mjahr from mkpf into table i_mkpf
      for ALL ENTRIES IN i_bkpf
     where mblnr = i_bkpf-awkey(10).
*     and   mjahr = i_bkpf-awkey+10(4).
ENDIF.
LOOP AT i_bkpf into wa_bkpf.
  READ TABLE i_mkpf into wa_mkpf
    with key mblnr = wa_bkpf-awkey(10)
             mjahr = wa_bkpf-awkey+10(4).
  IF sy-subrc eq 0.
     write:/ 'Accounting Document:', 23 wa_bkpf-belnr,
          35 'Material Document:', 55 wa_mkpf-mblnr.
  ENDIF.
ENDLOOP.
