Why dont you directly call the method from patterns button in SE38. Dont create a reference .

In pattern -> choose ABAP Object patterns.

Then give class -> CL_GUI_ALV_GRID and method SET_TABLE_FOR_FIRST_DISPLAY .

or if you want to create a new refernce to class in your program try this -

data: grid_custom_container TYPE REF TO cl_gui_custom_container,

grid_container TYPE scrfname VALUE 'MYGRID',

alv_grid tYPE REF TO cl_gui_alv_grid.

CREATE OBJECT grid_custom_container

EXPORTING container_name = grid_container.

CREATE OBJECT alv_grid

EXPORTING i_parent = grid_custom_container.

Cheers.

Did you try the othe method i.e. creating an insatnce of this class in your program.

data: alv_grid tYPE REF TO cl_gui_alv_grid.

CALL METHOD alv_grid->SET_TABLE_FOR_FIRST_DISPLAY

EXPORTING
I_BUFFER_ACTIVE =
I_BYPASSING_BUFFER =
I_CONSISTENCY_CHECK =
I_STRUCTURE_NAME =
IS_VARIANT =
I_SAVE =
I_DEFAULT = 'X'
IS_LAYOUT =
IS_PRINT =
IT_SPECIAL_GROUPS =
IT_TOOLBAR_EXCLUDING =
IT_HYPERLINK =
IT_ALV_GRAPHICS =
IT_EXCEPT_QINFO =

CHANGING

IT_OUTTAB = itab[]

IT_FIELDCATALOG =
IT_SORT =
IT_FILTER =
EXCEPTIONS
INVALID_PARAMETER_COMBINATION = 1
PROGRAM_ERROR = 2
TOO_MANY_LINES = 3

You have to replace 'me' to 'alv_grid'.

in the pattern wizard

pass the instance name (instance of the alv_grid) if you leave it blank system will use me and you have to manually change that.
