CRM WEB界面保存前增强小记

1.     对于订单类的保存前检查，可以调用BADI：Order_Save，以下是具体代码范例：

          在方法check_before_save中首先编写check逻辑，

          *定义参考的消息类
          DATA:lr_message_service TYPE REF TO cl_bsp_wd_message_service.
          lr_message_service = cl_bsp_wd_message_service=>get_instance( ).

          CALL METHOD lr_message_service->add_message
             EXPORTING
               iv_msg_type   = ‘E’
               iv_msg_id     = ‘XXX’
               iv_msg_number = ‘000’.

           RAISE do_not_save.    “通过调用自带的exception才能阻止程序流继续运行

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

＊另一种抛消息的方式，采用BOL编程

         DATA: lr_global_message TYPE REF TO cl_crm_genil_global_mess_cont.
         DATA core TYPE REF TO cl_crm_bol_core.
      

         core = cl_crm_bol_core=>get_instance( ).
         lr_global_message = core->get_global_message_cont( ).
         CHECK lr_global_message IS BOUND.
         lr_global_message->add_message( iv_msg_type   = ‘E’ iv_msg_id = ‘XXX’ iv_msg_number = ‘000’ iv_show_only_once = abap_true ).

2.     对于BP主数据的保存前检查，可以调用BADI：BUPA_FURTHER_CHECKS

       在方法CHECK_CENTRAL中首先编写check逻辑，

         DATA: lw_return TYPE bapiret2.

         lw_return–type = ‘E’.
         lw_return–id = ‘ZFR_001’.
         lw_return–number = 016.
         lw_return–message_v1 = org_name1.
        APPEND lw_return TO et_return.                 “通过向方法自带的ET_RETURN中写入参数，可以阻止程序流继续运行
