ABAP-ALV可编辑字段没有传入内表

问题：在ALV界面中输入可编辑字段的值，点击保存按钮，这个值并没有传入程序内表。

 

解决方法：在点击按钮的操作之后加入获取屏幕值的方法。

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
        IMPORTING
          E_GRID = LR_GRID.
CALL METHOD LR_GRID->CHECK_CHANGED_DATA.

 一个具体使用场景：

FORM FRM_USER_COMMAND USING R_UCOMM LIKE SY-UCOMM
                             RS_SELFIELD TYPE SLIS_SELFIELD.
  READ TABLE GT_ALV INTO WA_ALV INDEX RS_SELFIELD-TABINDEX.
  CHECK SY-SUBRC = 0.

  DATA: LR_GRID TYPE REF TO CL_GUI_ALV_GRID,
        MYINDEX TYPE SY-TABIX.

  CASE R_UCOMM.
    WHEN '&SAVE'.
      CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
        IMPORTING
          E_GRID = LR_GRID.
      CALL METHOD LR_GRID->CHECK_CHANGED_DATA.
      RS_SELFIELD-REFRESH = 'X'.
      PERFORM FRM_SAVEDATA.
  ENDCASE.
  RS_SELFIELD-REFRESH = 'X'.
ENDFORM.
