CL_GUI_ALV_GRID Problems when using enter and f4 in one ALV

Question

Hi guys,
i have the following problem:
I Use a ALV, which has a column MATNR. The ALV provides the standard search help for this field automatically. so far so good. BUT i also need to read additional data, such as GLD, Material shortext etc, when the users presses the Enter Key.
Here is my coding:
      CLASS lcl_events DEFINITION
CLASS lcl_events_0300 DEFINITION.
  PUBLIC SECTION.
    METHODS:
      handle_data_changed
            FOR EVENT data_changed OF  cl_gui_alv_grid
            IMPORTING er_data_changed sender.
ENDCLASS.                    "lcl_events DEFINITION
The problem that occurs: if i select a material via f4, i just can add one material to the alv. if i place the cursor into the second line, press f4 again, the alv overwrites the MATNR in the first line
i think the problem has to do with the fact, that the alv runs throug my enter event, when pressing f4.
thats how i registered my event:
  g_o_alv_grid_bart_0300->register_edit_event(
  EXPORTING
   " i_event_id = g_o_alv_grid->MC_EVT_MODIFIED ).
     i_event_id = g_o_alv_grid->mc_evt_enter ).
...und EventHandler zuweisen
  CREATE OBJECT g_o_alv_events_0300.
  SET HANDLER g_o_alv_events_0300->handle_data_changed FOR g_o_alv_grid_bart_0300.
kind regards, mark

Answer 1

Sorry for forgetting the impl. part of the class!
      CLASS lcl_events_0300 IMPLEMENTATION
CLASS lcl_events_0300 IMPLEMENTATION.
  METHOD handle_data_changed.
HandleDataChanged                  ***
    DATA: ls_good                TYPE lvc_s_modi.
     FIELD-SYMBOLS: .
alle Inhalte der geänderten Zellen in die interne Tabelle schreiben
    LOOP AT er_data_changed->mt_good_cells INTO ls_good.
Dazu auf die richtige Zeile in der ITAB positionieren:
      READ TABLE  INDEX ls_good-row_id.
      IF sy-subrc = 0.
Und das geänderte Feld dem Feldsymbol zuweisen
        ASSIGN COMPONENT ls_good-fieldname OF STRUCTURE .
        IF sy-subrc = 0.
Feldwert zuweisen
          -matnr
        AND bwkey = werks.
  ENDLOOP.
Und neu ausgeben
    g_o_alv_grid_bart_0300->refresh_table_display( ).
  ENDMETHOD.                    "handle_data_changed
