    METHODS get_data RETURNING VALUE (gt_mara) type t_mara.

  PRIVATE SECTION.

    DATA:gt_mara TYPE STANDARD TABLE OF mara-matnr.

    TYPES:t_mara TYPE TABLE OF mara-matnr.

ENDCLASS.

CLASS z_model IMPLEMENTATION.

  METHOD get_data.

    SELECT matnr from mara into table gt_mara

      where matnr eq 'dlsadla''.

Hi,

why did you declare gt_mara in private section ?

Hi Fred,

Even if I remove it from private section and declare globally, still im getting the same error.

try like this:

*----------------------------------------------------------------------*

*----------------------------------------------------------------------*

CLASS z_model DEFINITION.







  PUBLIC SECTION.



    TYPES: BEGIN OF tp_mara .

    TYPES: matnr TYPE mara-matnr .

    TYPES: END OF tp_mara .



    TYPES: tp_mara_tab TYPE STANDARD TABLE OF tp_mara WITH NON-UNIQUE KEY matnr .



    METHODS get_data

      RETURNING value(it_mara) TYPE tp_mara_tab .



  PRIVATE SECTION.



ENDCLASS.                    "z_model DEFINITION

*----------------------------------------------------------------------*

*----------------------------------------------------------------------*

CLASS z_model IMPLEMENTATION.



  METHOD get_data.





  ENDMETHOD.                    "get_data



ENDCLASS.                    "z_model IMPLEMENTATION

Forgot to add:

INITIALIZATION .



  DATA: it_mara TYPE z_model=>tp_mara_tab .



  DATA: z_model_obj TYPE REF TO z_model .



  CREATE OBJECT z_model_obj .



  it_mara = z_model_obj->get_data( ) .
