What is the distinction between an adapter versus the adapter engine? How are the 2 related?
Also, what is the process flow of a message?
Step 1. Adapter
Step 2. Integration Engine
Step 3. Adapter
What are the steps in between? I am trying to put together a diagram of a message flow in XI. Any help is appreciated!
Basically adapter run time is Adapter engine. you do all configurations for an adapter in the integration directory and in the run time adapter engine processes the message using the configuration specified in integration directory.
process flow will be on high level, as you specified
adapter engine---> Integration Engine --> (adapter engine)
You dont have any steps in between, but inside Integration engine the message flow through pipeline steps/services.

Hey Archana,
So is it safe to say that the actual adapter is part of the adapter engine?
In my diagram, I want to say:
Step 1. Adapter picks up file
Step 2. Adapter -> Adapter Engine
Step 3. Adapter Engine -> Integration Engine
Step 4. In Integration Engine, message gets transformed
Step 5. Integration Engine -> Adapter Engine
Step 6. Adapter Engine -> Adapter
Step 7. Adapter drops off/delivers file
Would that be a safe assumption, or are you saying to get rid of steps 2 and 6?
In your diagram, you should represent the adapter engine is one big box and inside that box, you will have small boxes for each adapter(file, RFC, http) etc.
So, from the file adapter box inside the big adapter engine box, you should have link to File directory box from where you are getting the file.
technically your steps are right, but in the diagram since adapter box will be inside the adapter engine box, you dont have to show the steps 2, 6 specifically in the diagram.
>>>>1. The Integration Server contains the Adapter Engine and Integration Engine.
2. Adapters run on the Adapter Engine.
both are true
for more try any XI book like mine
that shows XI compoentns

Hi Daniel -
<i>>>>1. The Integration Server contains the Adapter Engine and Integration Engine.</i>
Yes, Integration Server is pretty much synonymous with "XI". It also houses/contains the Business Process Engine (e.g. for ccBPM).
<i>>>>2. Adapters run on the Adapter Engine.</i>
Basically yes.
If you have access to the SAP Service Marketplace, there's a good presentation on <a href="http://service.sap.com/~sapidb/011000358700004078552003E/PIAdapterFramework.pdf">Adapter Framework and Adapter Strategy</a> that includes a good architecture diagram that might clear some things up.

have a look at
