Hi,

Look at the follow example. I hope it's usefull for you.


CLASS mar_test DEFINITION.

  PUBLIC SECTION.

"   Defining a method with a returning parameter
    METHODS get_value
            RETURNING value(r_data) TYPE REF TO data.

ENDCLASS.                    "mar_test DEFINITION

*----------------------------------------------------------------------*
*       CLASS mar_test IMPLEMENTATION
*----------------------------------------------------------------------*
*
*----------------------------------------------------------------------*
CLASS mar_test IMPLEMENTATION.

  METHOD get_value.

    FIELD-SYMBOLS <variable> TYPE ANY.

    DATA v_variable TYPE char2.
"   Here we're creating a new reference to Data v_variable
    CREATE DATA r_data LIKE v_variable.

"   Moving the reference to a field-symbols
    ASSIGN r_data->* TO <variable>.

"   Manipulating the content of the reference through field-symbols <variable>
    MOVE 'AB' TO <variable>.

  ENDMETHOD.                    "get_value

ENDCLASS.                    "mar_test IMPLEMENTATION

DATA o_mar_test TYPE REF TO mar_test.
DATA v_variable TYPE char2.
DATA v_value TYPE REF TO data.

FIELD-SYMBOLS <variable> TYPE ANY.

START-OF-SELECTION.

  CREATE OBJECT o_mar_test.

" The method returns the reference of a data into v_value
  v_value = o_mar_test->get_value( ).

" You can't access directly the Content of reference so, you must use
" dereferencing operator ->* to move values to a field-symbols
  ASSIGN v_value->* TO <variable>.
" After make the dereferencing you can move the value of field-symbols to any Compatible Data
  MOVE <variable> TO v_variable.

" Now you can work with a Data that contains the value returned from method
  WRITE v_variable.

Regards.
