Example: RFC to SOAP scenario

RFC - Sender interface or source interface is outbound (outbound from source system)

SOAP - Receiver or target interface is inbound (inbound to target system)

>what shall i select service interface category option and why?

you can also select category outbound for sender and inbound for target interface

Hope that helps.

Hi Pooja,

You can refer to the link http://wiki.sdn.sap.com/wiki/display/XI/FeaturesaddedinServiceInterfacePI7.1andOtherEnhancementsinPI7.1 to understand more on service interface.

Also you can check the below link where sample scenario was explained for RFC to SOAP

Thanks,

Hi Pooja,

Rajendra explains very clear on this sometimes confusing terminology.

I have just one little piece of background to add:

As it was explained to me one day during XI course is that SAP did not want to make XI the centre of the universe, so they looked at the Message (now Service) Interfaces from the sending and receiving application point of view.

So from Sender point of view it's outbound, from Receiver point of view it's inbound.

Hi Pooja,

In help.sap page for SAP XI you will get lot of info about service interfaces. I will try to briefly explain this.

There are mainly 3 kinds of Service interfaces are there in SAP PI. Previously these are called as Message interfaces.

1. Outbound Interfaces: If message with payload(xml) is coming from outside party (eg.System A) and entering into PI system, then you call it as outbound interface.

2. Inbound Interfaces: if message is goinf out from PI system to Target system (eg. System B) then you name it as inbound interfaces.

3. Abstract interface: which is not having any direction ans it is used in the ccBPM scenarios because ccBPM uses only abstract interfaces(direction-less).

For your RFC to SOAP scenario. For RFC message Type you should select Outbound interface, and for SOAP message type you need to select Inbound Interface. You scenario looks like as follow:

System A -> RFC adapter (Outbound Interface) ->PI -> SOAP adapter (Inbound Interface) -> System B

Thanks,
