前言
前面介绍了Abap ALV的整体可编辑、列可编辑和单元格可编辑，但是有时会有根据行项目某个字段的值来控制其他单元格的可编辑性的需求，其中还涉及到ALV刷新的功能。
实战
单元格数据修改后自动刷新
单元格中的数据被修改后，将ALV单元格中的数据立即刷新到ABAP对应的内表中：
方法一：通过对REUSE_ALV_GRID_DISPLAY函数参数i_grid_settings-edt_cll_cb进行设置：
i_grid_settings-edt_cll_cb = 'X' .
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTINGi_grid_settings = i_grid_settings
方法二：通过函数参数I_CALLBACK_USER_COMMAND指定的回调Form的参数slis_selfield进行设置：
FORM user_command USING ucomm LIKE sy-ucommselfield selfield TYPE slis_selfield.
selfield-refresh = 'X'.
CASE ucomm.
WHEN 'UPDATE'.
PERFORM frm_update.
ENDCASE.
ENDFORM.
