Is there any way to find the parent process Id for the start process

Question

Hi Team, 
 In my process one of the process triggered unwanted scenarios and if I want to check parent process for the process. But I am unable to find it due to start process triggered the process. Do you know any other way to find the parent process Id or process name. (only for start process). Subprocess we can do by parentprocessid function. 
 Thanks, 
 Pradeep Sridharan

Did you try using the parent_process_id() function?

I don't know of any way of doing this for the start process node. Only way would be to run a process report with a search for a PV that is found in both processes.

I agree with the prior suggestions of passing it in as a parameter if you need it. Can you tell us anything more about your use case for needing it from the process called via Start Process node?

Pradeep Sridharan There isn't a built-in way to directly track the parent process Id for subprocesses launched by a start process. There are strategies you can implement during process design to improve in future. When launching a subprocess from the start process, consider passing relevant data as input parameters. You can set dynamic name of process using parent process data to track back easily.

Pradeep Sridharan said: For that issue tracing purpose I want to check which parent process has triggered. 
 You haven't shared many details here about what data your parent (calling) process might have in common with the process facing errors, however if there are any pieces of data that can generally pinpoint what parent might have called a certain instance, you should be able to design a custom Process Report and surface that data in one or more displayed columns, then query the parent instances using Query Process Analytics to try and determine matches. 
 You haven't said what you ultimately plan to do with the parent instances (if anything) or even if they're still active, but this might give you a start.

Pradeep Sridharan In the past, we ran into this problem. We can investigate by looking at the main process's timestamp when it started. If we find subprocesses with timestamps around that time, and examine their data, there might be a connection. This approach takes a bit longer, but you can try it. Let me know if that works for you.
