Try using "CHECK_CHANGED_DATA" to check if data is changed. Following link may be useful for you:

Hi,

Check Method REFRESH_TABLE_DISPLAY of Class CL_GUI_ALV_GRID.

You can see Demo Programs provided by SAP by going to SE38 and see programs starting with BCALV.

Thanks

Hello, when you press BACK button, you have to free the objects relationed to ALV into the MODULE PAI

PROCESS AFTER INPUT.

MODULE user_command.

CASE sy-ucomm.

WHEN 'BACK'.

LEAVE ..... -> Return to previous screen

* Free objects

go_grid->free( ). -> DATA: go_grid TYPE REF TO cl_gui_alv_grid.

go_custom_container->free( ).

-> DATA: go_custom_container TYPE REF TO cl_gui_custom_container.

* Clean objects

CLEAR: go_grid, go_custom_container.

ENDCASE.

ENDMODULE.

I hope this help you.

Hi,

Few points to confirm.

1. Probably the output table is not cleared after each display. There must be some condition in your program like,

if it_data is initial.

fetch data.

endif.

If, so remove that condition.

If still not working, at start of selection, after the user inputs data, before fetching data from database, clear the data table.

start of selection.

clear it_data.

select .....

2. The call for ALV display should be something like this.

if CONT1 is initial.

create object cont1 exporting container_name = 'CONT1'.

create object grid1 exporting i_parent = CONT1.

call method grid1->set_table_for_first_display

exporting

i_structure_name = 'itab'

is_layout = s_layo

changing

it_outtab = it_data

it_fieldcatalog = it_fieldcat.

else.

call method grid1->refresh_table_display.

endif.

3. In the PAI, use this code to return to initial screen.

MODULE user_command.

CASE sy-ucomm.

WHEN 'BACK'.

LEAVE to screen 0.

try this code.

data : ref_grid type ref to cl_gui_alv_grid.

* to reflect the data changed into internal table
         if ref_grid is initial.
           call function 'GET_GLOBALS_FROM_SLVC_FULLSCR'
             importing
               e_grid = ref_grid.
         endif.
         if not ref_grid is initial.
           call method ref_grid->check_changed_data.
         endif.

Hi,

Try using the method refresh_table_display of class cl_gui_alv_grid.

o_grid->refresh_table_display

Here o_grid is same as the ref which you are using for display the data.

Hi everyone,

i have solved the issue.

Both the answers given by Susmitha Susan Thomas and David Carballido worked for me.

By freeing the memory and by adding the refresh function worked for me.

Thanks for your instant replys.
