How to solve problem with where-used list?

Question

I've the problem that in many places of my FPM (floorplan manager, web dynpro) code the where-used list does not work anymore because the FPM functions force the developer to specify structure of column names by literals. So for example in the UIBB's GET_DEFINITION methods or when using the following piece of code in some PROCESS_EVENT function:
CASE io_event->mv_event_id.
     WHEN if_fpm_guibb_list=>gc_guibb_list_on_cell_action.
     io_event->mo_event_data->get_value(
          EXPORTING
               iv_key = if_fpm_guibb_list=>gc_event_par_column_name
          IMPORTING
               ev_value = lv_col_name
          if ( lv_col_name = 'FOO' ).
          endif.
endcase.
Here one must comapare (line 9) the variable lv_col_name with some literal containing the name of an element of a structure. So the where-used list on STRUCT-FOO does not find this source. Is there any way to fix this problem? I thought to use RTTI for it, but could not find any way to do this. Possibly, is there any pragam or pseudo comment to update the where-used list of a specific structure at a given place?

Answer 1

The point is that when I start using RS_ABAP_SOURCE_SCAN I have to remember to do this I don't like the situation that after changing some name of a structure's element, the source code of the whole application is correct, no error will occur but the behaviour of the application may be totally wrong. Possibility a better solution will be to add some constants containing the structure element names to the model class of the FPM application.
