SAP SD交货单凭证流里的Confirmation of Service初探 II
1，经过研究与测试，confirmation of service也是可以被取消的。
如果交货单被取消了PGI，则confirmation of service也会自动跟着取消。
上图中的Cancel service 1053840000就是在PGI被取消（VL09）之后，自动生成的一个号码。
2，Confirmation of service还可能会在如下场景里出现，比如一些服务的销售。我们定义了服务物料号，将服务料号写在销售订单里。相关的schedule item category的定义里（VOV6）不设置移动类型。
如果相应的SO item出现在Delivery里，当我们对交货单在VL02N里做了PGI过账后，SAP系统并不会产生物料凭证号，而是会出现confirmation of service号。具体见如下例子（该例子来自互联网）。
An example of a Confirmation of service
1. A sales order is created. This sales order contains a schedule line category that does not have a movement type maintained in transaction VOV6.

2. Sales Order is delivered. The created delivery will not have a movement type.

3. The “Post Goods Issue” button is pressed in transaction VL02N.
4. GM status is now “C”. No material document was created, but a “Confirmation of Service” exists in the document flow.
