cl_gui_alv_grid-check_changed_data issue

VenuAnumayam — Thu, 17 Dec 2009 19:33:35 GMT

Hello,

I am using method "cl_gui_alv_grid->check_changed_data" in an editable ALV program like this.

module user_command_0100 input.
data: l_valid type c.

    case ok_code.
     when 'EDIT'.
      call method plan_grid->check_changed_data
                importing e_valid = l_valid.


     if l_valid = 'X'.
      perform update_data.
     endif.

The issue is, even if no records were changed on the ALV output, the method is returning l_valid = 'X'.

Can I use l_valid as a flag to determine the data was changed?

Thanks.

Hi,

Try to debug inside the method and see why the flag is set as 'X' evenif there is no data change.

I think that the method tells you if there is any error on your ALV so you can save it without problems...remember that you can control errors when a particular field has changed.

In that case, the 'l_valid" is not a "true" flag for finding out if the data was changed or not but it is for determining if there are any errors or not.

That's what I think...but I'm not completely sure... -:)
