Inbound and outbound handling

[Former Member]

What is inbound and outbound in sap xi / pi ?

According to my knowledge, a message coming to xi is called inbound message and going out of xi is called outbound message. Is this correct or any thing else is there ?

What is inbound interface and outbound interface ?

If the data is going out of the system, it is called outbound and if it is coming in to the system, it is inbound with respect to that system.

You must observe that the inbound and outbound notation is made in reference to the external systems and not to Integration Server. So, outbound interface refer to messages which come out of sender system, and inbound interfaces refer to messages which go into receiver system.

Once you do an Integration Scenario in repository and see the integration schemes from the point of view of application servers (and not of the integration server) you will understand the notation.

Incase of Integration Engine, it gets data from outbound interface and sends data to inbound interface.

Please let me know if you still have doubt.

Hi Rajesh,

Inbound and  Out bound is determind w.r.t the Backend system, not XI. Let's say you have a proxy-to-file scenario. You are getting data from SAP backend system and sending it to XI by 1 interface and sending it to third party system from XI using another interface. 

So the former interface is outbound in terms of backend SAP and the later interface is inbound w.r.t the thrd party system. Hence, the former is Outbound and the later is inbound. Please refer the below figure. 

Hope this helps.

Cheers,
