Scenario on HTTP Client to RFC
By Viswanadh, PI Competency Team, YASH Technologies
This document describes how the HTTP Client
Communicates with SAP R/3 System using SAP XI. In this scenario represented
pictorially, a client is going to place HTTP request to XI server by sending an
XML message, where in XI is going to transform the request from HTTP to a RFC
call to SAP R/3 system.

are obligatory to be able to generate a message.

< hostname: port > : Host and
port of the HTTP proxy
< path > : /sap/xi/adapter_plain
<query-string > : Namespace
optional ( party, scheme ,
