BPMN-Question

wir33658

Sorry, maybe not the absolute right place, but could not find anything for leading the question directly to the BPMN Spec guys.

In the BPMN Spec 2.0 (found on http://www.bpmn.org/) I could not find any description for sub-processes being able to use a reference to an already created BPMN-process. It looks like each time you have a sub-process you need to define it there.

The reuse of already created processes as a sub-process within another process seems not possible to me. I hope I am wrong, otherwise the re-useability is pretty poor in BPMN and you would have to define many times the same thing. If I am wrong, could anybody tell me how a reference to a process as a sub-process will be defined within the BPMN 2.0 notation.

Thanks.

Cheers, Rob.

Hi,

I think you looked at embedded sub processes, which are not reusable.
Reusable sub processes are created just like a normal process and invoked from a main process with a call activity.

Best regards,

The call activity, is it an Activiti specific matter or a BPMN Spec matter ? I looked up in the BPMN 2.0 Spec for something like this, but could not find anything.

Maybe you can point it out to me.

Are you sure?

10.2 Activities
An Activity is work that is performed within a Business Process. An Activity can be atomic or non-atomic
(compound). The types of Activities that are a part of a Process are: Task, Sub-Process, and Call Activity, which
allows the inclusion of re-usable Tasks and Processes in the diagram. However, a Process is not a specific graphical
object. Instead, it is a set of graphical objects. The following sections will focus on the graphical objects Sub-Process
and Task.

Read the Spec pretty much (about 500 pages 😉 but I guess I did not quiet understand the Call Activity. If this is the right mean for what I was asking for - great. I go and study it in more detail.

Thanks pointing it out to me.

Cheers, Rob.
