SAP MM VL34事务代码批量创建Inbound Delivery
标准系统中，采购订单里的confirmation control key为0004（inbound delivery）的时候，
去执行VL34，才能顺利为该采购订单去创建inbound delivery，
去看采购订单item的confirmation Tab,
如果是其它confirmation control key 比如0007等，可以使用VL31N去手工创建inbound delivery,而VL34却不能成功执行。
也即是说VL34要想成功执行，对于confirmation control key是有讲究的。
关于后台配置，
Go to SM30 > Table V_T163L > Click Maintain > click on the check box "Create Inbound delivery" against the conformation control key used in PO. i.e 0004.
Maintain conformation control key in "Conformation" TAB of PO.
You can set up so that inbound deliveries are only created automatically for Order Type/plant/storage location combinations.
SPRO > Logistics Execution > Shipping >Deliveries > Define Order Confirmations for Inbound Deliveries.
