SAP S4HANA里委外加工采购功能的变化

【Part 1：主要变化点】

1.1,采购订单界面上的变化，

1.2, 新的事务代码: ME2ON (Subcontracting Cockpit),

1.3, 新的事务代码: ADSUBCON （Subcontracting Monitor）

【Part 2, 新旧事务代码之间的区别】

2.1, 在ME2O和ADSUBCON，只会产生541移动类型的物料凭证号。

2.2, ADSUBCON is the newly defined transaction code which is provided as part of EP4 (Enhancement Package 4) recently by SAP to enhance the external refurbishment of MRO items using subcontract process. Basically, they are serving the same purpose (that is in support for subcontract process). However, ADSUBCON is a much more powerful transaction (than ME2O) as you can use it to convert subcontract PR into PO, stock transfer posting to your subcontractor as well as posting GR with reference to subcontract PO thereafter. It is considered as ''Subcontract Monitoring Cockpit'' transaction.

2.3, 而在ME2ON 事务代码里，可以实现2步法（movement type 30A）将子件库存转移过账到分包商库存里。

【Part 3, 两步法将子件转移过账到分包商库存】

如果要2步法来实现委外采购流程，大致的操作步骤如下：

1) 创建一个采购订单，ITEM Category设置为L，然后维护分包BOM；

2) 执行ME2ON事务代码，highlight the Component Line，点击'Create Delivery'按钮；

3) 在创建交货单提示界面里，将移动类型由541修改为30A。保存，创建交货单单据。

4) 为交货单拣配然后做发货过账。

5) 此时去看component part的库存，就能看到其库存处于状态'ST'（Stock for SC）；

6) 一旦分包商说他完成了相关加工工序，我方可以执行MIGO + 30B O 将子件料号的特殊库存状态由'ST'变为'O'。

7) 等分包商将加工好的料号送到我方，我方就可以执行MIGO + 101为回收件料号做收货，同时消耗子件的库存。

移动类型30A和30B，
