Hi,

we have a method named as SET_TABLE_FIRSTDIsplay which is used to display the alv report.

CALL METHOD grid->set_table_for_first_display

EXPORTING

I_BUFFER_ACTIVE =
I_BYPASSING_BUFFER =
I_CONSISTENCY_CHECK =
I_STRUCTURE_NAME =
IS_VARIANT =

i_save = 'A'

I_DEFAULT = 'X'

is_layout = gs_layo

IS_PRINT =
IT_SPECIAL_GROUPS =
IT_TOOLBAR_EXCLUDING =
IT_HYPERLINK =
IT_ALV_GRAPHICS =
IT_EXCEPT_QINFO =
IR_SALV_ADAPTER =

CHANGING

it_outtab = gt_final

it_fieldcatalog = gt_field

it_sort = gt_sort

IT_FILTER =

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

Hi ,

For displaying report output using OOP's ALV,you can check this demo program

Hope this may be helpful.

Hi Jean,

First add a container on the screen to hold the ALV Grid and name it 'PO_CONTAINER'.

Now, use this demo code:-
