SAP 实时获取ALV界面编辑内容（ALV刷新功能）

如何获取当前ALV界面的编辑列内容

实现代码如下：

FORM frm_user_command USING p_ucomm  TYPE sy-ucomm
                            rs_selfield  TYPE slis_selfield.
data:  ls_stbl            TYPE lvc_s_stbl,
       lo_grid            TYPE REF TO cl_gui_alv_grid.

 CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
    IMPORTING
      e_grid = lo_grid.

  CALL METHOD lo_grid->check_changed_data
    IMPORTING
      e_valid = lv_valid.

rs_selfield-refresh = 'X'.

ls_stbl-row = 'X'." 基于行的稳定刷新
  ls_stbl-col = 'X'." 基于列稳定刷新
  CALL METHOD lo_grid->refresh_table_display
    EXPORTING
      is_stable = ls_stbl
    EXCEPTIONS
      finished  = 1
      OTHERS    = 2.

ENDFORM.
