Function Modue with Dynamic Table as output parameter

Question

Hi experts,
i have function (below) which reads "dynamically" data from table which is specify as input parameter, the data are "saved" in <ft>.
How can i return <ft> as output parameter of function module (table) ?
function
import parameter  - > IC_TABLE
source code
data :   lt_OPTIONS   type standard table of RFC_DB_OPT,
         lt_fields    type standard table of rfc_db_fld,
         lt_data      type standard table of tab512,
         la_rfcdata   type tab512,
         la_rfcfields type rfc_db_fld,
         lr_dref      type ref to data.
field-symbols: <ft>         type table.
field-symbols: <structure>  type any.
field-symbols: <field_to>   type any.
field-symbols: <field_from> type any.
CALL FUNCTION 'RFC_READ_TABLE'
  EXPORTING
    query_table                = IC_TABLE
  DELIMITER                  = ' '
  NO_DATA                    = ' '
  ROWSKIPS                   = 0
  ROWCOUNT                   = 0
  tables
    OPTIONS                    = lt_OPTIONS
    fields                     = lt_fields
    data                       = lt_data
EXCEPTIONS
   TABLE_NOT_AVAILABLE        = 1
   TABLE_WITHOUT_DATA         = 2
   OPTION_NOT_VALID           = 3
   FIELD_NOT_VALID            = 4
   NOT_AUTHORIZED             = 5
   DATA_BUFFER_EXCEEDED       = 6
   OTHERS                     = 7.
  create data lr_dref type table of (ic_table).
  assign lr_dref->* to <ft>.
Fill data from OLTP table into ct_table.
  assign local copy of initial line of <ft> to <structure>.
  loop at lt_data into la_rfcdata.
    loop at lt_fields into la_rfcfields.
      assign component sy-tabix of structure <structure> to <field_to>.
      if sy-subrc is initial.
        assign la_rfcdata+la_rfcfields-offset(la_rfcfields-length)
          to <field_from>.
        <field_to> = <field_from>.
      endif.
    endloop.
    append <structure> to <ft>.
  endloop.
Thanks in advance

Hi Martin,
parameters with generic types are not allowed. So TYPE ANY TABLE etc. will not work. As Alex alreads said, you could return a reference to your table.
Your parameter should be typed like:
re_table type ref to data.
At the end of your function module get a reference of your table into your parameter:
get reference of <ft> into re_table
After the call of your function module you can now handle and work with your table as wished:
* Declaration
data: re_table type ref to data.
field-symbols: <my_table> type standard table.
* Assign reference to fieldsymbol
assign re_table->* to <my_table>
if sy-subrc NE 0.
" Error: Could not assign reference
endif.
Best regards,
Fabian
