Routing Configuration 
A Business Scenario enables you to completely model a business process, including the exchange of all messages relevant for the business process.
To guarantee that the receivers can be identified successfully at runtime, administrators must define the flow of messages in the system landscape when configuring the routing You also have the option here of specifying conditions to control the forwarding of the message between a sender business system and one or more receiver business systems.
The configuration object that you must define for this is the routing relation.

Since routing relations are grouped within Business Scenarios and since Business Scenarios can be transported as independent objects, it is possible to activate all routing relations that belong to a Business Scenario just for production operation.

Routing relations are displayed in the navigation area of the Integration Builder under Business Scenarios.
You can do the following with the Integration Builder at configuration time:
· Create Business Scenarios in the Integration Directory to group routing relations
· Display/Change Routing Relations
You also have the option of defining routing conditions within a routing relation.
