How to modify the field symbol

Question

Hello Every1,
I have a internal table and field symbol with the below structure.
Data : begin of itab occurs 0,
           matnr like mara-matnr,
           ersda like mara-ersda,
       End   of itab.
FIELD-SYMBOLS: <Matnr>    TYPE STANDARD TABLE.
I have the field symbol with 10 records similar to the structure of itab. (Only matnr is populated and date as initial). Now I need to transfer the date value from itab to the field symbol for the matching matnr.
Please let me know how to do it.
Thanks,
Siva.

Sivaprakash,
To my knowledge, a field-symbol cannot hold values on its own. It refers to a field or a table and work directly with the values.
Your scenario cannot be achieved unless there is another internal table besides itab.
Create a field-symbol of type itab2 and compare matnr with itab-matnr.
If a record is found then move the date field to <fs>.
Your code may look like this.
loop at itab2 assigning <fs>.
   read table itab into wa_itab with key matnr = <fs>-matnr.
if sy-subrc = 0.
  <fs>-date = wa_itab-date.
endif.
endloop
Thanks,
