ABAP-OOALV-回车事件:

首先要为ALV_GRID设置enter事件：

  CALL METHOD GO_ALV_GRID->REGISTER_EDIT_EVENT
    EXPORTING
      I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_ENTER
    EXCEPTIONS
      ERROR      = 1
      OTHERS     = 2.

然后编写事件接收器:
CLASS CL_EVENT_RECEIVER DEFINITION.
  PUBLIC SECTION.
   " ENTE时触发
    METHODS HANDLE_ENTER
           FOR EVENT DATA_CHANGED_FINISHED OF CL_GUI_ALV_GRID
        IMPORTING E_MODIFIED ET_GOOD_CELLS.

  PRIVATE SECTION.
ENDCLASS.                    "CL_EVENT_RECEIVER DEFINITION

CLASS CL_EVENT_RECEIVER IMPLEMENTATION.
  " 实现ENTER 事件方法
  METHOD HANDLE_ENTER.
    DATA GS_LAYOUT_ALV TYPE LVC_S_LAYO.
    DATA : LV_STABLE TYPE LVC_S_STBL.

    PERFORM FOM_REFRESH .

    LV_STABLE-ROW = '1'.
    LV_STABLE-COL = '1'.

    GS_LAYOUT_ALV-CWIDTH_OPT = 'X'.

    CALL METHOD GO_ALV_GRID->SET_FRONTEND_LAYOUT
      EXPORTING
        IS_LAYOUT = GS_LAYOUT_ALV.

    CALL METHOD GO_ALV_GRID->REFRESH_TABLE_DISPLAY
      EXPORTING
        IS_STABLE = LV_STABLE.

      CALL METHOD CL_GUI_CONTROL=>SET_FOCUS
        EXPORTING
          CONTROL = GO_ALV_GRID.
      CALL METHOD CL_GUI_CFW=>FLUSH.

  ENDMETHOD.                    "HANDLE_MODIFY

ENDCLASS.                    "cl_event_receiver IMPLEMENTATION
