Target entity type doesn't match flowchart target type..

[lj4353]

I created a parent process and a sub-process. I want them to process asynchronously.

I tried using Sub-Process and Event Sub-Process, but neither worked. I set Multi-Instance=true for the Sub-Process. What should I do to make them asynchronous?

I want the parent process to finish without waiting for the sub-process to complete.
