用ME_CONFIRMATION_UPDATE处理采购订单行项目确认视图

用function module： ME_CONFIRMATION_UPDATE ，可以处理采购订单行项目确认视图，实现增删改操作。

CALL FUNCTION 'ME_CONFIRMATION_UPDATE'
         EXPORTING
           I_EBELN =    " 采购订单号        TABLES
           XEKES   =    "对应新增和修改
           YEKES   =    "对应删除

因为没有找到读取采购订单行项目确认视图的函数，所以自己写了一个：

CALL FUNCTION 'ZPP142_GET_EKES'
       EXPORTING
         I_EBELN =    " 采购订单号= '00010'   " 采购订单行项目
       TABLES
          T_ekes  =   "读取的确认视图表

ZPP142_GET_EKES 的代码：

data t_ebelp type ebelp.
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      INPUT         = i_ebelp
   IMPORTING
     OUTPUT        = t_ebelp
            .

   select * from ekes into table t_ekes
        where ebeln = i_ebeln
          and ebelp = i_ebelp. 
 
对确认视图做增删改的代码例子如下：
 
REPORT  ZTEST0.

data: lt_xuekes type table of UEKES,
       ls_xuekes type UEKES.


data: lt_ekes type table of ekes,
       ls_ekes type ekes.

data op type c.

 op = 'U'.    "修改
*op = 'D'.   "新增
*op = 'I'.   "删除

case op.

   when 'U'.


*读取确认
     CALL FUNCTION 'ZPP142_GET_EKES'
       EXPORTING
         I_EBELN = '4900177648'
         I_EBELP = '00010'
       TABLES
         T_ekes  = lt_ekes.
     .
*准备修改现有条目
     loop at lt_ekes into ls_ekes.
       MOVE-CORRESPONDING ls_ekes to ls_xuekes.
       ls_xuekes-eindt = '20180303'.
       ls_xuekes-kz = 'U'.
       append ls_xuekes to lt_xuekes.
       clear: ls_ekes.
     endloop.

     if lt_xuekes is not INITIAL.
       CALL FUNCTION 'ME_CONFIRMATION_UPDATE'
         EXPORTING
           I_EBELN       = '4900177648'
         TABLES
           XEKES         =  lt_xuekes
*    YEKES         =
                 .

       if sy-subrc = 0.

         commit WORK AND WAIT.
         write 'update ok'.
       else.
         write 'update not ok'.
       endif.
     endif.

   when 'I'.
