Start process flow from process flow

Hi,

I want to start a process flow from another process flow. 

When I have reached the end of proces flow 1, I want to start process flow 2 .

Process flow 2 is also used without process flow 1, by a table task.

My idea was to use the ‘Execute table task’ action at the of process flow 1 which is the starting point of process flow 2. However, this does not work.

How can I make this work? Do I need to make process flow 2 available via the API and then call it from process flow 1. Is that an idea?

Thanks,

Peter
