Hello Swamy

Below you find sample coding for your problem:


DATA: lt_knb1   TYPE knb1.

FIELD-SYMBOLS: <ls_knb1>   TYPE knb1.
FIELD-SYMBOLS: <ls_record> TYPE any,
                            <ls_fld>       TYPE any.

" Typed field symbol
LOOP AT lt_knb1 ASSIGNING <ls_knb1>.
  <ls_knb1>-ernam = syst-uname.  " directly modifies itab contents
ENDLOOP.

" Untyped field-symbol
LOOP AT lt_itab ASSIGNING <ls_record>.

  DO.
    ASSIGN COMPONENT syst-index OF STRUCTURE <ls_record> TO <ld_fld>.
    IF ( syst-subrc NE 0 ).
      EXIT.
    ENDIF.

    <ld_fld> = "...".   " directly modifies itab contents
  ENDDO.

ENDLOOP.

Regards
