How to move the two itab into third itab

Question

Hi sap guru ,
my question : i have 3 internal table (i_vbrk , i_vbrp and itab)
1.i_vbrk like vbrk .
DATA: BEGIN OF I_VBRK OCCURS 0 ,
     VBELN LIKE VBRK-VBELN ,
     FKDAT LIKE VBRK-FKDAT ,
     FKART LIKE VBRK-FKART ,
     KUNAG LIKE VBRK-KUNAG ,
     END OF I_VBRK .
2.i_vbrp like vbrp .
DATA: BEGIN OF I_VBRP OCCURS 0 ,
      VBELN LIKE VBRP-VBELN ,
      MATNR LIKE VBRP-MATNR ,
      WERKS LIKE VBRP-WERKS ,
      END OF I_VBRP .
but for THIRD internal table which i have ' itab ' should be having same FIELDS like both internal table (i_vbrk and i_vbrp)
so  I have ,
3. ITAB .
TYPES: BEGIN OF ITAB  ,
       VBELN TYPE VBRK-VBELN,
       FKDAT TYPE VBRK-FKDAT,
       FKART TYPE VBRK-FKART,
       MATNR TYPE VBRP-MATNR,
       WERKS TYPE VBRP-WERKS,
       KVGR1 TYPE VBRP-KVGR1,
       END OF ITAB .
IS THIS RIGHT ....
NOW I WANT THAT THE DATA WHICH I WILL FETCH FROM DB-TABLE FOR THOUSE TWO INTERNAL TABLE (i_vbrk and i_vbrp) SHOULD MOVE INTO THIS THIRD ITAB ..PLZ TELL ME WHAT WILL BE THE CODE FOR THAT ?
answer will be rewarded....

Hi,
  Common suggestion can be to use 'INNER JOIN' but to have
a good performance of the code You can try the following.
types : BEGIN OF t_VBRK,
VBELN LIKE VBRK-VBELN ,
FKDAT LIKE VBRK-FKDAT ,
FKART LIKE VBRK-FKART ,
KUNAG LIKE VBRK-KUNAG ,
END OF t_VBRK .
types : BEGIN OF t_VBRP,
VBELN LIKE VBRP-VBELN ,
MATNR LIKE VBRP-MATNR ,
WERKS LIKE VBRP-WERKS ,
KVGR1 TYPE VBRP-KVGR1,
END OF t_VBRP .
TYPES: BEGIN OF ITAB ,
VBELN TYPE VBRK-VBELN,
FKDAT TYPE VBRK-FKDAT,
FKART TYPE VBRK-FKART,
MATNR TYPE VBRP-MATNR,
WERKS TYPE VBRP-WERKS,
KVGR1 TYPE VBRP-KVGR1,
KUNAG LIKE VBRK-KUNAG , 
END OF ITAB .
data : i_vbrk type STANDARD TABLE OF t_vbrk,
       wa_vbrk type t_vbrk.
data : i_VBRP type STANDARD TABLE OF t_VBRP,
       wa_VBRP type t_VBRP.
data : i_itab type STANDARD TABLE OF itab,
       wa_itab type itab.
*/////write the select statements here.....//////
loop at i_vbrk into wa_vbrk.
  wa_itab-vbeln = wa_vbrk-vbeln.
  wa_itab-FKDAT = wa_vbrk-FKDAT.
  wa_itab-FKART = wa_vbrk-FKART.
  wa_itab-KUNAG = wa_VBRK-KUNAG.
  READ TABLE i_VBRP into wa_vbrp
  with key vbeln = wa_itab-vbeln.
  wa_itab-MATNR = wa_vbrp-MATNR.
  wa_itab-WERKS = wa_vbrp-WERKS.
  wa_itab-KVGR1 = wa_vbrp-KVGR1.
  append wa_itab to i_itab.
endloop.
