IDoc#4096出现如下报错：
Conventional invoice verification no longer maintained as of Release 4.6
详细报错信息：
Conventional invoice verification no longer maintained as of Release 4.6C
Message no. M8893
Diagnosis
As described in the Release Notes for 4.6C, conventional invoice verification is no longer subject to maintenance. Online transactions for conventional invoice verification have been removed from all menus. If you use EDI, we would like to call your attention to the improvements that have been made.
System Response
IDoc document processing is terminated. No invoice documents are created.
Procedure
Reset your Customizing to logistics invoice verification by changing the process code from INVM to INVL. You can find more details in our online documentation in the Basis Services/Communication section (BC-SRV) under IDoc Interface: EDI Application Scenarios (BC-SRV-EDI).
背景是：这个IDoc是一个公司间STO的流程里，Billing过账后自动通过输出类型RD04触发的。
执行事务代码WE20, 维护Vendor对应的partner profile,
将Process code由INVM改成了INVL.
重新Process这个IDoc, 这个报错就不再出现了。
