Routing Relation 

Definition

Routing Relation

In a routing relation, the possible receivers for the messages of an outbound interface are defined for a sender. For a routing relation, you have the option of specifying the conditions that should apply when forwarding a message to the receiver(s).

There are two ways of identifying the receiver:

·        Receiver business system(s) is specified explicitly when configuring the routing. Here you have the option of specifying a routing condition for forwarding the message to the receiver(s). This condition is analyzed at runtime.

·        Receiver business system is determined at runtime from the contents of the message (payload).

For more information, see Defining a Receiver.

Routing Condition

The distribution of the message to one or more possible receivers is controlled through a routing condition. A routing condition usually refers to the application data from the payload.

In the Business Scenario example Book a Flight Trip, the following is a possible routing condition: “Send message for checking flight availability to receiver business system AIR_LH of airline Lufthansa if field Airline_Id in the payload of the message has the value LH (Lufthansa).”

Routing conditions are specified in the language XPath.
