Using field symbol on export parameter

Question

HI All,
I am using this logic In few methods of mine and I wonder if there is option the create one method
and every time that I need it just call it.
The issue is that <lt_output> is not assign yet (this need to happen in the method itself )so And I need to export it
and if I am creating method with exporting field type any I put the field symbol there I am getting dump.
Any idea ?
ASSIGN COMPONENT lv_table_out
            OF STRUCTURE is_response TO <lt_output>.
  IF sy-subrc <> 0.
    READ TABLE it_map INTO ls_map INDEX 1.
    lv_out = ls_map-left.
    ASSIGN COMPONENT lv_out
    OF STRUCTURE is_response TO <lt_output>.
  ENDIF.
Best regards
Joy

Hi,
Ok, then you will have to use a data object to reference your field symbol and use a returning parameter I guess:
DATA: lo_data TYPE REF TO data.
FIELD-SYMBOLS: <lt_output> TYPE ANY.
CLASS lcl_main DEFINITION.
  PUBLIC SECTION.
    CLASS-METHODS: get RETURNING value(r_val) TYPE REF TO data.
ENDCLASS.                   
CLASS lcl_main IMPLEMENTATION.
  METHOD get.
    FIELD-SYMBOLS <fs> TYPE ANY.
    ASSIGN COMPONENT 1 OF STRUCTURE is_response TO <fs>.
    GET REFERENCE OF <fs> INTO r_val.
  ENDMETHOD.                    "get
ENDCLASS.                  
START-OF-SELECTION.
  lo_data = lcl_main=>get( ).      
  ASSIGN lo_data->* TO <lt_output>. 
Kr,
m.
