Scenario on RFC to SOAP

By Viswanadh, PI Competency Team, Yash Technologies

In this blog, we will discuss on how to design and configure a scenario to use sender RFC adapter and receiver SOAP adapter. 


RFC adapter in XI Adapter Engine supports Secure Network Communications (SNC). It is used to get connected to SAP R/3 system, used for synchronous communications and receive RFC messages when triggered in SAP R/3 System. SNC protects the data communication paths between the various components of the SAP System.

RFC adapter converts the RFC data into RFC XML (XML message format) and send it Integration engine for further processing using the pipe line steps. 

SOAP adapter in XI Adapter Engine is used to exchange SOAP message between Integration server and Web service servers. Though you can specify security settings to be used to sign/verify the message to add security to the message exchange, scenario is developed selecting HTTP as transport protocol and SOAP 1.1 as message protocol. 

The scenario in this posting is to trigger RFC message to XI that will send SOAP message to Web Service server to execute its method like sending a SMS to remote mobile and gets the response message and passes it to source R/3 System. 

Find below the step-by-step procedure to achieve this scenario: 

Development in R/3 System:

a.      RFC is created at the R/3 side with the following parameter 


Designing activities in Integration Repository:

1.       Enable the option “import of RFC/IDOC permitted” of Software component version to import RFC into XI as illustrated in below:


No need of Creating Objects for Outbound Interface when we import the RFC from R/3 system, we get the relevant Data Type, Message Type and Message Interface along with it. 

2.       In this scenario we are using method “SendSMSToIndia” from Free Web Service of “webservicex”.

So, the scenario has been made interesting which would send an SMS to a remote mobile.

The SendSMSToIndia Method sends the SMS to Given Mobile Number as Input parameters   

SendSMSToIndia Method

Input parameters:

                        Mobile Number, FromEmailAddress, Message

Output information:

                        FromEmailAddress, Mobile Number, Provider,      State, Status      

3.       SOAP Connection parameters would be as follows:

Target URL   :

SOAP Action:   http://www.webserviceX.NET/SendSMSToIndia

Ø       Inbound Data Type 

For Inbound data type, download the WSDL file 

SAVE as SendSMS.wsdl and create a new External Definition using the SendSMS.wsdl WSDL File


4.       Create Outbound Message Interface

5.       Create Inbound Message Interface


6.       Create Message Mapping to convert RFC structure to Web Service Request

7.       Create another Message Mapping to convert Web service Response to RFC Response


8.       Create Interface Mapping

Save the objects and activate them.
