Questions about Direct Communication

Hi Experts,

I am now reading materials about Direct Connection in PI 7.1, and have the below questions about it.

Please kindly help to answer, any advice is appreciated.

1. We have Direct Connection object in ID, and in help.com we have a lot of information explaining Direct Communication.

Are they the same thing? When we say Direct Communication, does this mean Direct Connection has to be used in scenario?

2. in SAP NetWeaver Process Integration - Configuring Web Service Scenarios document@2.1.2.2 Scenarios Using Direct Communication, "The back-end systems can either be ABAP-based or Java-based."

However, in help document, Configuring Direct Communication, "At present, this mechanism can only fully propagate the configuration data to those back-end systems that are based on AS ABAP."

Really confused about this if Direct Communication and Direct Connectin are the same thing we are talking about.

Does this mean only ABAP based backend systems can be used in Direct Connection scenario?

3. There is document "Point-to-Point Direct Connection Design and Configuration in SAP using NetWeaver Processing Integration 7.1" from William Li, it is mentioned "If any of the business systems is an SAP system, then ABAP proxies will have to be generated on the corresponding backend SAP system, using the interfaces in the previous step." There is no according infomation about this step in help document, this step is majorly for?

This is somehow a bit long, thanks your opnion and effort in advance.

Best Regards,

IMO, both Direct communication and Direct connection refers the same. Through Direct connection(point to point communication) we can let two web service runtime of SAP systems can communicate and without using Integration server (central instance). That means we dont gain any middleware features such as mapping or CCBPM or monitoring. We will use web security features using the direct connection object like WSRM etc.

In ESR we need to create data types, mesg types and Service interfaces. In the ID, we will do one comm channel (WS adapter for reciever) and direct connect object to communicate between two SAP Systems. Proxies will be generated before activating ID objects for both sender and reciever.

If sender system A sends proxy request that message is routed via PI direct connection object to System B.

Looks like. But if the sender system is different than SAP system then we might have to use Direct connection using Message broker as Integration server. This case PI integration server is involved. This is not point to point communication.

Williams' s document talks about direct connection for point to point communication. This design for communication between sap systems. The other mode is using Integration server.

Direct communication applicable to only based on AS ABAP based systems only and to integrate SAP system which has AS ABAP then we can use Difrect communication
