@vemulabujji From your parent process, collect the results as list as you mentioned result list =[“PI”,“DV”,“SI”,“PA”] . After the service task create a multi-instance call activity to start the subprocesses in parallel as per the below model.
lets say your result list variable is subProcessList=[“PI”,“DV”,“SI”,“PA”] and assign a element variable as subProcesskey to loop through the list elements and it will be assigned to the calledElement attribute of call activity. (refer the diagram)
