e_ucomm problem

Former Member — Mon, 15 Sep 2008 20:35:06 GMT

hello,

in my data_changed method I am doing a check on e_ucomm which is the function code of a context_menu in an ALV-Grid.

method handle_data_changed.
    if e_ucomm = 'Context_menu_AAS'.
      /bmw/pur_a003_cl_inbox_appl=>gv_verantw_flag = 'X'.
    endif.

Unfortunately the handle_data_changed is triggered also by pressing ENTER on the grid. I found out that e_ucomm is still set to value 'Context_menu_AAS' and is not set for exampe on initial.

Can I somehow clear the content of e_ucomm?

I tried

method handle_data_changed.
    if e_ucomm = 'Context_menu_AAS'.
      /bmw/pur_a003_cl_inbox_appl=>gv_verantw_flag = 'X'.
     clear e_ucomm.
    endif.

But that did not have any effects on future calls of handle_data_changed.

had somebody had the same experience?

with best regards

Hello Luchticha

I would recommend to define an instance (static) attribute in your event handler class, e.g.:


CLASS lcl_eventhandler  DEFINITION.
  " NOTE: I prefer to use static methods and attributes for my event handler class, but this is a matter of taste...
  PUBLIC SECTION.
    CLASS-DATA:
      md_okcode       TYPE ui_func.  
    CLASS-METHODS:
      handle_data_changed
         FOR EVENT data_changed OF cl_gui_alv_grid
             IMPORTING er_data_changed,


    handle_onf4 FOR EVENT onf4 OF cl_gui_alv_grid
          IMPORTING sender
                 e_fieldname
                 e_fieldvalue
                 es_row_no
                 er_event_data
                 et_bad_cells
                 e_display.

ENDCLASS.                    "lcl_eventhandler DEFINITION

When the user chooses a function of the context menu it should trigger event USER_COMMAND. Here you can store and refresh you attribute, e.g.:


METHOD handle_user_command.

  md_okcode = e_ucomm.
" Do something...
  CLEAR: md_okcode.
ENDMETHOD.

Perhaps you need another place where to clear the ok-code but I think you understand the concept and can easily adapt this to your scenario.

Hi Luchticha ,

You can define another variable like e_ucomm. Then you can modify your code something like this:

data: l_ucomm like e_ucomm

method handle_data_changed.
    l_ucomm = e_ucomm.
    if l_ucomm = 'Context_menu_AAS'.
       clear: e_ucomm,l_ucomm.
      /bmw/pur_a003_cl_inbox_appl=>gv_verantw_flag = 'X'.
    endif.

Hope this will change your problem.

Unfortunately the problem remains.

I tried to clear e_ucomm on various places, but it is not set to INITIAL.

Maybe anybody else has an idea what happens?

thx

Hello Luchticha

I have some problems understanding why you need to know E_UCOMM (triggered by choosing a context menu function) at the event handler HANDLE_DATA_CHANGED. Perhaps you can explain your scenario or show parts of the relevant coding.

I will try to explain better,

in my data_changed method I am doing a check on e_ucomm which is the function code of a context_menu in an ALV-Grid.

method handle_data_changed.
    if e_ucomm = 'Context_menu_AAS'.
      flag = 'X'.
    endif.

I need this because if handel_data_changed is triggered by clicking on the context-menu some error checks, which will be called later in this method, must not be done. I am doing this by checking whether the flag is set or not.

Till here everything works fine, but if I change a field in the ALV and press Enter (which triggers handle_data_changed) e_ucomm is still set to 'Context_menu_AAS' and so the flag is set again to X and the error-checking again is not done which is wrong.

However, shouldn't the u_ecomm not be initialized automatically?

I tried

Hello,

I am not sure the problem is still alive.

I faced the same problem and found a solution to clear the e_ucomm.

The user command is stored in CL_GUI_ALV_GRID->M_UCOMM.

The data_changed event is triggered as follows:

raise event data_changed exporting er_data_changed = mr_data_changed

e_onf4 = i_f4

e_onf4_before = i_f4_before

e_onf4_after = i_f4_after

e_ucomm = m_ucomm.

so all we need do is to clear M_UCOMM.

There is a method:

CL_GUI_ALV_GRID->SET_USER_COMMAND

exporting

i_ucomm = space.

I hope this helps!
