Unable to Assign Feild Symbol to the Internal Table

[atslokesh]

While creating a field symbol to the Internal Table, I'm getting this error, Please guide me

    READ TABLE it_ptr_mail1 ASSIGNING <fs_ptr_mai> WITH KEY pid = <fs_ptr_bal>-pid BINARY SEARCH.     <br>    IF sy-subrc = 0.<br>      w_final_bal-mail_id = <fs_ptr_mai>-emailid.<br>    ENDIF.<br>

you have forgot:

Field-Symbols <fs_ptr_mai> Type ANY.

or

READ TABLE it_ptr_mail1 ASSIGNING field-symbol(<fs_ptr_mai>) WITH KEY pid = <fs_ptr_bal>-pid BINARY SEARCH.

You must declare the field symbols before using them (FIELD-SYMBOLS <...> ...), or declare them through "Inline Declaration" (FIELD-SYMBOL(<...>)), as Frederic explained.
