SubProcess not instantiated

Camunda 7 Topics Discussion & Questions

Hello,

I am totally new to Camunda, so this might be a frequent asked question, but I couldn’t find an answer yet.
I have create a simple BPMN workflow with a Call Activity which calls a sub process in the same BPMN model.

But I get the following error:

Cannot instantiate process definition Demo:9:e60db97a-57ce-11ea-ad8f-0242ac110002: no processes deployed with key ‘SubProcessA’ and tenant-id ‘null’: processDefinition is null [ start-instance-error ]

Simple.bpmn (3.9 KB)

Seems to be a greenhorn problem, but I couldn’t find anything in the documentation.

Thanks for any help!

Hi Clemens,

It’s a misunderstanding about how Call Activities work.
They can’t call sub processes - they call other process models or other pools.
At this point of the advanced symbols tutorial, it’s explained in detail how to use a call activity. Hopefully that’s useful to you.

Hi Niall, thank you for the very quick reply. Yes, I got this one wrong. I’ll take a look at the video, thanks for the link!

Hi @ClemensTan,

it was indeed recently asked: Multiple use of embedded subprocess

Hope this helps, Ingo

Hi Ingo, thanks for the post, that would have been my next question, if there is a way to embedded multiple subprocesses. That answered my question and I am glad, that this is possible!
