drop down field auto update on alv grid display

[vieet]

Hi Gurus,

I am using cl_gui_alv_grid and my requirement is I have having 100s of records in the internal table and there is dropdown functionality for remarks.
When the user selects the value in the first record the same should be able to reflect for all the records in the same column rather than user
manually selecting each and every one.

I could able to manage to get into the internal table by looping the record and passing the fixed value but upon using refresh_table_display it is not getting updated on the screen.
I mean I can not able to see the first dropdown value in the rest of the fields.
I have tried with passing stable parameter to the refresh_table_display but no luck.
I just want to see all the columns of the dropdown field gets filled when I select in the first row with the same value.
Kindly help me with it as it is urgent requirement from the business.

Please consider the object gv_alv3 in the below screenshot as gv_alv is altogether different screen.

In debugging I could able to see the remarks column getting updated with values for all records but when I do F8 it is not visible on the grid.
