_"Hello,

I have got some quite complex business processes tomodel, and here is my first question. I was wondering how we coulddesign this particular situation :

• Imagine a quite complex and long process.
  -At anytime an external actor could send a mail which will cause thisprocess to be interrupted causing a new process to be launched toprocess the mail. We cannot go further in the main process until themail is processed.
  
• Once the mail is processed, we need to resume the main process.
  

How could I represent this in BPMN ?

Does this representation seems ok to you ?_

_
Thanks very much in advance"_

That wouldn't work, since it would restart the embedded subprocess.

You should use BPMN 2.0 for this, which includes event subprocesses exactly for this situation. It would look something like this.

I agree that the event-subprocess is a good choice here. It comes in two flavors, Interrupting and non-interrupting. The proposal by Michael Rowley indicates a non-interrupting behavior. However, you said you wanted a pause-resume behavior. That is not specified in BPMN. What you can do is: interrupt the subprocess and find a way to trigger it again. E.g. through recuston?
