20170228 ALV method中用E消息,会退出到初始界面;STOP 会dump;
再回车就处理界面了,
所以,Handel_data_change 做数据检查时,如果需要报错要用到,
CALL METHOD er_data_changed->add_protocol_entry EXPORTING i_msgid = ‘Z_BH1‘ i_msgno = ‘000‘ i_msgty = ‘E‘ i_msgv1 = ‘你输入的起始日期大于结束日期!‘ i_msgv2 = ‘‘ i_msgv3 = ‘‘ i_fieldname = ls_modi-fieldname i_row_id = ls_modi-row_id.
可参考
