Automatic ALV refresh and display

Former Member — Tue, 13 May 2008 09:13:18 GMT

Im creating a ALV automatic refresh report. I have set the timer for every 10 seconds. I have set the breakpoint in the Select statement up to 5 rows and find initially , the internal table contains items 0 ,1,2,3,4 and after 10 seconds(setting the timer for 10 seconds) , itab contains items 5,6,7,8,9.

This is fine.

Im trying to display this is ALV. The initial ALV with items 0,1,2,3,4 is found wherease even after 10 secons the values in the ALV are not changing to 5,6,7,8,9. They remain in the initial state.

Kindly help me how to chnage the data in the ALV grid after refresh is happening without any USERCOMMANDS ( ie , data changed in the ALV grid every 10 seconds without any user interaction)

Thanks

Hi,

The following method call is used to refresh the data displayed within an ALV object grid:

CALL method gd_tree->REFRESH_TABLE_DISPLAY.

CALL METHOD gd_tree->set_table_for_first_display

EXPORTING

is_layout = gd_layout

CHANGING

it_fieldcatalog = gd_fieldcat

it_sort = it_sortcat

it_outtab = it_report.

CALL method gd_tree->REFRESH_TABLE_DISPLAY.

CALL METHOD cl_gui_cfw=>flush.

Regards,

Bhaskar

the problem still persists. the ALV gets refreshed and timer works properly still change in the display of data in the ALV grid does not happen.

I just need the contents of the ALV to change when refreshed which is not happening . I can find this happening only when i set a break point and not on the output screen . Kindly help me to solve this. Any samples
