  • 增强小记02

    想在ME21N保存前做一些数据检查,

    可以做一个增强功能,

    运行 CMOD 新增,   增强接口 输入 MM06E005  (  EXIT_SAPMM06E_012 ) ,在 NCLUDE ZXM06U43 .  里写代码功能。

    例子如下:

    *&---------------------------------------------------------------------* *&  包括                ZXM06U43 *&---------------------------------------------------------------------* TABLES: EKPO.

    DATA: e_message(200) TYPE c. DATA: SPSTYP LIKE EBAN-PSTYP. DATA: SBANFN LIKE TEKPO-BANFN. DATA: t_msg(200) TYPE c. DATA: t_answer(1) TYPE c. data: iflag type i.

    IF I_EKKO-BSART = 'KSUB' OR I_EKKO-BSART = 'EUB'.   iflag = 0.   LOOP AT TEKPO.     SPSTYP = 0.     SBANFN = TEKPO-BANFN.     SELECT SINGLE * FROM EBAN WHERE BANFN = SBANFN.     IF SY-SUBRC = 0.       SPSTYP = EBAN-PSTYP.     ENDIF.

        if SPSTYP = 3.        iflag = iflag + 1.

          if iflag = 1.           CONCATENATE '注意:请购单' SBANFN INTO t_msg.       else.

              CONCATENATE t_msg '/' SBANFN INTO t_msg.         endif.     endif.

      ENDLOOP.

      if iflag > 0.     CALL FUNCTION 'POPUP_WITH_2_BUTTONS_TO_CHOOSE'       EXPORTING *       DEFAULTOPTION = '1'         DIAGNOSETEXT1 = t_msg *       DIAGNOSETEXT2 = ' ' *       DIAGNOSETEXT3 = ' '         TEXTLINE1     = '是: L 类型的请购单允许转为 U 类型的采购单'         TEXTLINE2     = '否: L 类型的请购单不允许转为 U 类型的采购单,先删除再保存' *       TEXTLINE3     = ' '         TEXT_OPTION1  = '是'         TEXT_OPTION2  = '否'         TITEL         = '选择'       IMPORTING         ANSWER        = t_answer.

        IF t_answer = 2.       CONCATENATE '申请单:' SBANFN '是L类型,与当前类型不符!' INTO e_message.       message e_message type 'E'.     endif.   endif.

    ENDIF.

    这个功能会弹出一个用户选择的小窗口:

    如果选择“是” ,系统会继续保存,“否” 则出现错误提示,不能保存。
