Message flow direction
What exactly is the message flow direction ? In a sender system does the message moves from adapter engine to integration server or viceversa ? Similarly in a receiver system does the message move from Integration server to adapter engine ?

The messages are picked up by the sender communication channel, send to resource adapter in adapter engine which does the required formats into xml.
Then it goes to Module Proccessor and all module works on this in a perticular manner.
then it goes to in a queue, and all the basic routing and mapping part is done here
and then it goes to Integration server Messaging Queue.
To receive the messge from Integration server Messaging Queue and upto receiver end whole process is done in reverse manner.
If the adapter involved is a Java based adapter, then the flow would be
Sender - Adapter Engine (sender) - Integration Engine - Adapter Engine (receiver) - Receiver
If say sender adapter is ABAP based, then it would be
Sender - Integration Server (Idoc/HTTP Adapter) - Integration Engine - Adapter engine (receiver) - Receiver
