Hi Laxmikant,

If I have understood your requirement correctly, you need to update an internal table with latest 'value_new' from cdpos table where  'fname' = 'fieldname' .

Hope the below logic will help you:

FIELD-SYMBOLS: <wa_intab> LIKE LINE OF lt_intab.  "the internal table you want to change

LOOP AT lt_intab ASSIGNING <wa_intab> .

   READ TABLE lt_cdpos INTO wa_cdpos           "lt_cdpos contains latest data selected from CDPOS

    WITH KEY fname = <wa_intab>-fieldname.

   IF sy-subrc = 0.

     <wa_intab>-value = wa_cdpos-value_new.    

   ELSE.

     "//logic if the name is not there in CDPOS

   ENDIF.

   CLEAR  wa_cdpos.

ENDLOOP.

If you wish to improve performance, I suggest using

1. "transporting value_new" addition in READ TABLE,

2.  select only the data which you require from CDPOS,

3.  create the internal tables with only fields which you require,

4.  when you are using SELECT,LOOP AT statements, limit records by using WHERE condition
