Can one ESS 1.0 business package link to multiple clients in ECC6.0?

Hi everyone,

Have anyone successfully configure the following scenario? Appreciate your sharing how to achieve that:

Using EP7 with ESS 1.0 self-service business package, integrate with ECC6.0. Since ESS 1.0 are using WD applications, the communication is via the SAP JCo Connector which configure in the webdynpro administration. There are a few standard JCo connector need to configure in order to link the ESS 1.0 to the backend ECC6.0 such as SAP_R3_HumanResource; SAP_R3_HumanResource_MetaData. However, you can only specify one client in within the JCo connector. How to configure/setup to make it link to multiple clients in my ECC6.0 system?

Thanks & Regards,

Leonard
