refresh data in alv automaticly

former_member353207 — Wed, 23 Nov 2005 08:49:34 GMT

Hi,

I've an alv with a Z-Table. Data changes currently. I want the alv refreshing automaticly by every data-change (made by another program). I don't want to push a key.

a timer would be a solution, bu only the second-best.

Any ideas ?

Regards Joerg

Hi,

I think you can use class CL_GUI_TIMER to implement

timer in your program.

Eyal.

when ever there is a data change for refresh

you need to register an event

CALL METHOD G_GRID->REGISTER_EDIT_EVENT

EXPORTING

I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_MODIFIED.

then in that event You call method refresh

this will automatically refreshes.

In technical setting (SE11), you have an option: Log data change.

Maybe read the documentation.

But I'm not sure you could have an event, you could only create a log, and check in the log if something append to the table.

Joerg,

Try using the Method '<b>REFRESH_TABLE_DISPLAY</b>' present in the class 'CL_GUI_ALV_GRID'.

I hope this method would help.

Thanks

Vijay,

this is only 'normal' alv-code in PBO of dynpro '100':

DATA: ok_code LIKE sy-ucomm,

gt_meld TYPE TABLE OF zmeldung,

g_container TYPE scrfname VALUE 'ALV1',

grid1 TYPE REF TO cl_gui_alv_grid,

g_custom_container TYPE REF TO cl_gui_custom_container.

...

IF g_custom_container IS INITIAL.

CREATE OBJECT g_custom_container

EXPORTING container_name = g_container.

CREATE OBJECT grid1

EXPORTING i_parent = g_custom_container.

CALL METHOD grid1->set_table_for_first_display

EXPORTING

i_structure_name = 'ZMELDUNG'

CHANGING

it_outtab = gt_meld.

ENDIF.

....

Joerg,

Modify the code as follows:

IF g_custom_container IS INITIAL.

CREATE OBJECT g_custom_container

EXPORTING container_name = g_container.

CREATE OBJECT grid1

EXPORTING i_parent = g_custom_container.

CALL METHOD grid1->set_table_for_first_display

EXPORTING

i_structure_name = 'ZMELDUNG'

CHANGING

it_outtab = gt_meld.

<b>ELSE.

CALL METHOD GRID1->REFRESH_TABLE_DISPLAY.</b>

ENDIF.

Thanks,

Kam

Kam,

thanks, good idea. But it only works on new cycle PBO.

Maybe I try this in combination with Cl_Gui_Timer Class.
