Field-symbols as parameters to the method of a class

Question

Hi All,
I am having an doubt regarding the field-symbols.Can we pass the field-symbols as a parameter to the method of a class.If yes can anyone tell me how to do this. Before posting I have searched regarding it in google but I did not find any better solution.Though I have seen some examples regarding the passing of field symbols as a parameter those scenarios does not match with my report as my report varies dynamically based on selection criteria.
Below is the snippet of my code regarding the passing of field-symbols as a parameter.
methods:  final_data importing <fs_h_line>TYPE any
                                             <fs_h> TYPE STANDARD TABLE
                               exporting <fs_f_line> TYPE any
                                             <fs_f> TYPE STANDARD TABLE, 
CALL METHOD l_obj->final_data exporting <fs_h_line> = <fs_header_line>
                                                              <fs_h>      = <fs_header>
                                               importing <fs_f_line> = <fs_final_line>
                                                             <fs_f>      = <fs_final>.
With the above code I am getting an error.Check whether it is correct or not.If not suggest the solution to resolve the issue.

Hi
Maybe if you change this code below to field-symbol, it can work:
DATA: tl_header_csv TYPE STANDARD TABLE OF yol_header_arquivo,
      tl_csv_aux    TYPE textline_t                          .
DATA: wl_header_csv LIKE LINE OF tl_header_csv.
converter_csv_al11_itab( EXPORTING im_t_csv = tl_csv_aux
                         IMPORTING ex_w_sap = wl_header_csv
                         CHANGING  ex_t_sap = tl_header_csv ).
METHOD converter_csv_al11_itab.
  IM_T_CSV  Importing  Type  TEXTLINE_T
  EX_W_SAP  Exporting  Type  ANY
  EX_T_SAP  Changing   Type  STANDARD TABLE
