SAP: ALV GRID 追加复选框字段及编辑时立刻调用事件

10、在GRID界面中选择复选框时，提示以下信息：

运行时错误：MOVE_TO_LIT_NOTALLOWED_NODATA

短文本：Assignment error: Overwriting of a protected field.

错误分析： Field “<FS_VALUE>” was to assigned a new value but this field is at least party  protected against changes.

错误原因：

在218行的拼写有误：

CONCATENATE ‘GT_ITABL-’ ls_cells-fieldname into l_name .   将GT_ITAB 误拼写成GT_ITABL.
