Regarding changing data in Editable ALV Grid

[Former Member]

hi all,

I am displaying report some columns are editable. For getting data in editable columns i am using the method

IF NOT grid IS INITIAL.

CALL METHOD grid->check_changed_data .

ENDIF.

First time whatever i am editing i am getting in final O / P.

Second time when i entered the data and i am using the same method but this time i am not getting whatever i am chaging.

i am thinking that CALL METHOD grid->check_changed_data Grid is refreshing or some changes are happening.

How can i set grid to initial position.

Please suggest.

Hi,

Take a button with function code 'MODIFY' on which data needs to be modified in the alv output as well as internal table.

Use this code, its working:-

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

Tarun, you are great. This solution getting me changed data into my internal table. Thanks.

Hi Tarun,

I am using the class CL_GUI_ALV_GRID along with CL_GUI_CUSTOM_CONTAINER to display an ALV grid in a custom control container in a module-pool screen. The method CHECK_CHANGED_DATA captures the changed data (after clicking on the SAVE button) the first time. But it fails to capture from then on.

Please let me know what the problem is and how it can be solved.

Hi,

I am able to solve this issue using CALL METHOD G_CUSTOM_CONTAINER_I->free( ) in the user_command module of the second screen before calling the first screen.

module USER_COMMAND_1001 input.

ok_code = sy-ucomm.

CLEAR sy-ucomm.

IF ok_code = 'SAVE'.

PERFORM user_command_1001.

CALL METHOD G_CUSTOM_CONTAINER_I->free( ).

CALL SCREEN 1000.

ELSEIF ok_code EQ 'BACK' OR ok_code EQ 'EXIT' OR ok_code EQ 'CANC'.

LEAVE TO SCREEN 0.

ENDIF.

endmodule. " USER_COMMAND_1001 INPUT
