Conditionally start the process (process A is not over yet, process B cannot be started manually)

I have two processes, the initiators are the same, the first task of the B process will be automatically started after the A process ends

On the contrary, the A process is not over, and B cannot be started

Can someone give me some advice? I've tried throw and catch messages, but it doesn't seem to work.

Thanks.

Hi,

Shouldn’t process B be triggered by a call activity in process A ?

Yes, process B is independent and cannot be called in process A.
