ALV Grid Problem

Former Member — Mon, 10 Dec 2007 07:37:17 GMT

Hi,

I am facing one problem in ALV Grid. I am using OOPS ABAP for ALV Grid.

ALV Grid is in Edit mode. When I am changing data in the ALV, data is not getting reflected in the internal table.

Please give me the solution.

Regards,

Varun

Hi Varun,

You can try for grid method get_selected_rows.

CALL METHOD grid1->get_selected_rows

IMPORTING

et_index_rows = selected_rows.

it will get the index of that particular row that data have been changed.

then you can read your internal table as follows

READ TABLE i_itab INTO wa_tab INDEX sel_rows-index.

if sy-subrc = 0

modify wa_tab transporting <values>.

endif.

regards,

vikas.

plz reward if helpful.

Assuming that you are using CL_GUI_ALV_GRID then you have to call method go_grid->check_changed_data( ) at PAI of the dynpro displaying the ALV list in order to retrieve the data from the frontend (= ALV list) to your backend (= itab in ABAP program).

Place this method call as one of the first statements within your USER_COMMAND module (PAI) and the save will work.

For more details please refer to threads:

Where/how would you add the actual DB update to BCALV_EDIT_03?

"Implicit" Binding in ABAP OO?: the ALV method grid->check_changed_data
