1, 销售订单BOM组件分配前台操作

Tcode:CA02,输入物料，工厂，销售订单以及行项目，回车进入下一屏幕

点击组件分配按钮

选中要分配的行，点击 new assignment按钮，输入operation

保存。

2, CP_BD_DIRECT_INPUT_PLAN_EXT参数介绍

可以通过调用函数CP_BD_DIRECT_INPUT_PLAN_EXT实现销售订单BOM的组件分配，函数参数如下：

1， 输入参数

RC271_EX_IMP：

下图 routing head details中可以找到group和group counter

RC27M_EX：

SAVE_DI_IMP：

2, 组件分配相关tables参数

PLMZ_DI_EX_TAB：

          注意：BOMAT字段-->当bom header material（截图中编号18处）是phantom件（截图中编号19处勾上），需要向父层上找，一直找到不是phantom件的父层物料为止，

3, 例子程序

给销售订单BOM 940602-01的10行组件57432049分配0030的operation

程序如下：

REPORT ztest_component_allocate.

     l_rc27m_ex_imp     TYPE rc27m_ex,

     lit_text_di_tab    TYPE STANDARD TABLE OF tline,
