效果：
BADI：MB_MIGO_BADI
1、类的属性里添加了可以存储行项目的变量
2、IF_EX_MB_MIGO_BADI~LINE_MODIFY的方法被触发时将行项目数据传入GT_GOITEM中
代码：
IF cs_goitem-pps_aufnr IS NOT INITIAL AND cs_goitem-bwart = \'101\'. DELETE gt_goitem WHERE zeile = i_line_id. APPEND cs_goitem TO gt_goitem. ENDIF.
3、IF_EX_MB_MIGO_BADI~CHECK_ITEM的方法中循环读取GT_GOITEM中的行项目数据做处理即可
代码：

4、最后在IF_EX_MB_MIGO_BADI~POST_DOCUMENT中将属性GT_GOITEM清空
代码：
CLEAR gt_goitem.
