Former Member — Thu, 17 Jul 2008 21:51:09 GMT

Hi Gurus,

I am using refresh_table_display to refresh the data in my ALV, but apparantly it is not refreshing anything.

Please advice if i am missing something.

WHEN 'REFR'.

*Clear Data

PERFORM clear_data.

Data Selection.

PERFORM get_data.

CALL METHOD obj_grid->refresh_table_display

EXCEPTIONS

finished = 1

OTHERS = 2.

IF sy-subrc <> 0.

ENDIF.

ENDCASE.

Thanks in advance.

I think you need a " CALL METHOD cl_gui_cfw=>flush. " after the method refresh_table_display called.

You don't have to free the alv grid control.

This method is used to synchronize your SAPGui, each time you call it, a new RFC connection is opened to the SAPgui.

hi:

form user_com using r_ucomm like sy-ucomm

rs_selfield type slis_selfield .

case r_ucomm.

when: 'BACK' or 'EXIT' or 'CANCEL'. "leave back to last screen

leave to screen 0.

when: 'ZADD'. "add line

call screen '100' starting at 80 10.

when: 'ZDELETE'.

perform do_delete_line. "delete lines

endcase.

rs_selfield-refresh = 'X'.

rs_selfield-col_stable = 'X'.

rs_selfield-row_stable = 'X'.

endform. "user_com_second

if you used the oo ALV.

you need define a new object,do not use the old one.

such as:

FORM refresh_alv_dis.

data: l_grid TYPE REF TO cl_gui_alv_grid.

CALL METHOD l_grid->refresh_table_display.

ENDFORM. "REFRESH_ALV

好运，

Hi,

Why there is a need to FREE the custom container?

IF NOT G_CUSTOM_CONTAINER2 IS INITIAL.

CALL METHOD G_CUSTOM_CONTAINER2->FREE.

CLEAR: G_CUSTOM_CONTAINER2.

ENDIF.

CALL METHOD obj_grid->set_frontend_layout

EXPORTING

is_layout = ds_layo.

data ds_sort1 type LVC_T_SORT.

CALL METHOD obj_grid->get_sort_criteria

IMPORTING

et_sort = ds_sort1

CALL METHOD obj_grid->set_sort_criteria

exporting

it_sort = ds_sort1

CALL METHOD obj_grid->refresh_table_display

EXPORTING
