Routing
Use
Routing covers all rules that define the flow of messages between different systems at runtime. SAP NetWeaver PI supports in particular routing that depends on the content of the exchanged message. For example, you can define a routing rule of the form that all messages with a specific value of one particular message field will be sent to a specific receiver system.
For example, the Integration Engine detects messages where the customer number field has a specific value and forwards them to specific receiver systems, which are intended to handle requests coming from the corresponding customer.
The following figure shows a scenario where a message is forwarded to three different receivers:
