SAP CRM中间件架构的讨论：Multiple Exchange Projects - MEP

1084315 - Consulting: Information about the multiple backend scenario
Please refer to note 1084315. As mentioned in this note:
"objects CUSTOMER_MAIN, CUSTOMER_REL, MATERIAL, BUPA_KNVH, and DNL_CUST_PROD1 technically support the data exchange under MEP.

All other objects and transactional data in particular, are not supported."
客户incident里的对于单个CRM连multiple ERP有两个需求：

1.   The master data will be replicated from different ERPs to the same CRM(7.03), including customer, material, price records. For some countries, they have total different materials numbering, however, for other countries, they use the same material numbering with headquarter group.
   

2.   Meanwhile, transaction records (sales order) will be replicated to ERPs from CRM.
   

从tcode GNRWB里能很清楚得看到，SAP只支持上述五个adapter object的CRM<->ERP 1:N的连接。没出现在Repository object name column里的其他所有scenario均不支持。

关于CRM 的site维护里如果将CRM连接到多个ERP，这个在CRM tcode SEOEAC里是可以做到的，可以直接添加多个ERP system对应的entry，如图：
