Integration Server

Question

Hi SAP Gurus,
Please give me a generic answer, if you could:
How many pipelines are there in the Integration Server?
1. Receiver Identification, Interface Identification, Message Branch, Request Message Branch, Outbound Binding, Call Adapter, Request Message Mapping
2. Receiver Identification, Interface Identification, Message Branch, Request Message Branch, Outbound Binding
3. Message Branch, Request Message Mapping, Outbound Binding, Call Adapter, Request Message Mapping
Or may be I am asking the question wrong. Could someone please help.
Thanks,
Adnan Abbasi

Hi
pipeline is a set of services that process XML messages
on the integration engine
When a source message reaches the Integration server, it performs 6 steps before the message reaches the destination. The steps are:
1) Receiver Determination: This steps determines the system that participates in the exchange of the message.
2) Interface Detremination: For each receiver determine which interface will should receieve the message.
3) Message Split: If more than one receievers are found, Xi will instantiate new message for each receiver.
4) Message Mapping: Mapping to transform the source message to destination message format.
5) Technical Routing: Bind a specific destination and protocol to the message.
6) Call outbound Adapter: Send the transformed message to the adapter or a proxy.
One can examine these steps in Runtime Workbench using the Transaction: SXMB_MONI.
XI pipleine steps are-
Sender Agreement->Reciever Determination->Interface Determination->Interface Mapping->Reciever Agreement.
1) Sender adapter will poll the data into XI . This is carried out by Adapter Engine
Once it reached XI, it will in XI Message pipeline in the integration engine.
2) Reciever Determination is executed - to look into who is the reciever
3) Then Interface determination- Sender Interface and Reciever Interface Mapping
4) reciever Agreement- with adapter or proxy structure.
