Hi Manik,
You can use the Collect Statement.
The collect statement inserts the contents of a work area wa either as single row into an internal table itab or adds the values of its numeric components to the corresponding values of existing rows with the same key.
*So in your case the delivno matnr should be character*
and the  weight field should be numeric.
and also the order of fields in the internal table should be like that
first character fields then all the numeric fields.
SELECT BUKRS LIFNR BELNR BLART WAERS WRBTR
       FROM BSIK INTO CORRESPONDING FIELDS OF
       TABLE ITAB FOR ALL ENTRIES IN FILETAB WHERE
       BUKRS = FILETAB-BUKRS AND
       LIFNR = FILETAB-LIFNR AND
       BELNR = FILETAB-BELNR AND
       BLART = 'KR'.
LOOP AT FILETAB.
  LOOP AT ITAB WHERE LIFNR = FILETAB-LIFNR AND
       BELNR = FILETAB-BELNR.
      MOVE ITAB-BUKRS TO ITAB_FD-BUKRS.
      MOVE ITAB-LIFNR TO ITAB_FD-LIFNR.
      MOVE ITAB-BELNR TO ITAB_FD-BELNR.
      MOVE ITAB-BLART TO ITAB_FD-BLART.
      MOVE ITAB-WAERS TO ITAB_FD-WAERS.
      MOVE ITAB-WRBTR TO ITAB_FD-WRBTR.
      COLLECT ITAB_FD.
  ENDLOOP.
