Why not need to sender communication channel for IDOC etc.?

[Former Member]

can anybody give me the exactly explanation about why we don't need communication channel for sending IDOC/Proxy/HTTP/RFC but do for receiver side? i'm still a little bit confused...

many appreciation in advance.

This question answered many times in sdn,please search in sdn before posting:)

Sender Communication Channel adn sender agrement not required for IDoc ,HTTP adapters.these two adapters reside in ABAP Stack,that means in Integration Engine.The reason is that R/3 can directly send Idocs to XI via ALE layer using RFC destination specified in SM59. This IDoc after reaching XI is converted in IDoc-XML. This is done when we specify IDoc metadata IDX2 in XI. It is then used in IR for mapping.

Now for the receiver side, when IDoc-XML is created after mapping program run is sent to R/3. Before that, it has to

be converted into IDoc. This conversion is IDoc-XML to IDoc is done by IDoc Receiver adapter.

Hi Rajesh,

We do not create Sender Communication Channel for IDOC's and Proxy as its a direct Integration Engine to Integration Engine Communication. At R/3 side we do configurations where XI path details are mentioned and the Sender(R/3) knows whom to send the data to i.e SAP PI. Hence Sender Communications can be avoided and the IE of both (R/3 and PI) talk to each other directly.

But when it comes to the receiver end.....There is no way we can tell XI whom to send the data unless and until a receiver is configured.

Lets take it this way......how would XI know to whom to send data if no details of the receiver are feed to it.....??

Hence Receiver Channels are a must even in case of IDOCS and Proxy (which are suppose to be adapter less communication only when r/3 is Sender).

Hi Rajesh,

As per the architecture of PI - IDOC/Proxy/HTTP/RFC directly talks to Integration Engine and do not need any Adapters for the connection. You can read PI architecture and will get the more details on the same.
