BPM Sync Send Step & Correlation

[Former Member]

Hi Experts,

BPM Scenario: Step wise

1. Receive-1 from one sender

2. Send-1 it syncu2019ly to SAP using proxy and receive the response msg

3. N: 1 transformation b/w request message and response message to generate a target message

4. Send-2 the target message to a receiver

Though the scenario seems to be simple, I have a doubt about the sync send step.

How does the sync send step works in detail?

For every message the Receive-1 receives, a new process instance will be generated. When the message is sent to SAP syncu2019ly, how does it relate the response to the particular process instance?

For example, if 2 BPM process instances are created for two messages the Receive-1 step receives. However say, the second message is relatively less in size; in-turn consumes less time to execute in SAP and reaches XI well before the response for first message.

Which process instance will it be related to?

Please explain!

Thanks, Udo! With your reply I heave that itching thought.

I would happy to read more about this sync-session logic.

Can you please provide more information/ blog/ material for detailed info?

P.S. pts added to you!

Thanks,

Hi Kartik,

dont worry, request and response of a synchronous message are linked by a session; no confusion is possible. A correlation would be mandatory if you would have two asynchronous messages...

Thanks murali.

The link you have provided talks about "Composite Business Process from Scratch" but I am afraid I am lost.

Can you please highlight the point which you want to relate to my doubt?
