simple itab question

[Former Member]

hi

i have two itabs

ITAB1 with NAME field.

ITAB2 with NAME and MARKS fields.

if name in itab2 matches name in itab1 , i should assign marks 100 to that name.

i thought of coding this way.

loop at itab1.

loop at itab2 where name = itab1-name.

itab2-marks = 100.

endloop.

modify itab2.

endloop.

is it a right way of using modify command.

is there any way i can improve performance by sort method.

sort itab1 by name

sort itab2 by name.

loop at itab2.

read table itab1 with key name = itab2-name binary search.

if sy-subrc eq 0.

itab2-marks = 100.

<<update itab2.

endif.

endloop.

loop at itab1.

loop at itab2 where name = itab1-name.

endloop.

endloop.

Hi,

Please try this.

LOOP AT ITAB2.
  READ TABLE ITAB1 WITH KEY NAME = ITAB2-NAME.
  IF SY-SUBRC = 0.
    ITAB2-MARKS = 100.
    MODIFY ITAB2.
  ENDIF.
ENDLOOP.
