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.
