ESS MSS Multi-Client Configuration

Found a very Useful Blog by Srinivasan Govindaswamy. and presented it in my way.



This Post describes how to configure SAP Enterprise Portal to point to multiple backend clients in ESS/MSS scenarios.

Business Scenario

It is possible to maintain ESS/MSS landscape in a manner that allows multiple customers to be implemented within multiple clients on the same system with a unique Portal.

Below scenario shows a portal pointing to multiple clients from the same backend system containing ESS/MSS scenarios.
It is a pre-requisite that the usernames in backend clients and portal should be the same.
In this scenario, the users logged in to portal are able to access the backend using SSO logon tickets. 
Also, a Central User Administration (CUA) as to be implement in the landscape, one system or one client can dedicated for.






Single-Client Configuration Information


By default ESS/MSS is configured for a single backend client.
There are a number of configurations required in Portal as well as the backend like setting up JCo, System landscape, ADS and so on. 
The entire set of standard configurations can be found here:



Multi-Client Configuration Information

This Post assumes that all the ESS/MSS scenarios are working for a single backend client (e.g.: 100). 
(assumes already the Portal is configured with ESS MSS with ECC/R3/Backend client 100)

In the following steps we will configure the Portal to point to a new client (200) for ESS and MSS.







I have differentiated the Portal and Backend Configuration for Better Understanding.
