Get Tasks in Subprocess via parent process id

[Karthikeyan G A]

Dear All,

    Can we access the User Tasks in a child subprocess via the parent Process. 

Use case:

We have a insurance claims process that we are trying to design as the claim process is a large process, so we wanted to separate it into multiple subprocesses. While doing so we are facing one issue.

 > There are user tasks in subprocess. But We are unable to find the subprocess id from the parent process. 

Is there a way to get the user tasks of the child sub-process using the parent process?
