Babu,

Stateless : The ordinary integration, that is just receiving a message and sending it to receiver.

Statefull : In BPM you could do some decision based on previous messages by techiniques like correlations, so each sessions are maintained. Relation between messages are maintained.

Yes babu, in simple terms u can say

the message which enetes the BPE(business process Engine) are stateful.

i mean<b> if ur scenario include BPM, then u r doing stateful integration.</b>

Actually in without BPM scenario...message transmission happens via Integration server.message do not enter into BPE....so its <b>stateless</b>!!

But in BMP scenarios message transmits via BPE (where all BMP related message are processed)...so its<b> stateful</b>

If messages are not persisted inside integration server, then it is known as stateless

<i>Business Process Management provides SAP Exchange Infrastructure with functions for stateful message processing: The status of an integration process is persisted on the Integration Server. This means that you can specify how long an integration process must wait for further messages to arrive, for example. Furthermore, this enables you to process messages within an integration process further still; for example, you can collect certain messages and then send them in a particular order</i>Message was edited by:

Hi Babu,

If messages are not persisted inside integration server, then it is known as stateless. These are the normal async or sync scenarios.

When messages are persisted inside XI for their use further, then it is known as stateful communication. This is achieved using BPM functionality and Business Process Engine component of Integration Server.
