Trying to capture data in multiple nested sub-process and passing it back in the last nested subprocess after every process (except parent) has completed multiple times.

Have you tried passing the value by reference? By passing a reference to the actual parent process variable instead of its value, the data remains synchronized at all times. Any changes made to the a process variable in the parent process immediately update all referenced sub-process parameter values. Similarly, changes to the referenced value in the sub-process are concurrently reflected in the parent.

Although this article helped a lot, I still have a minor issue. Is there any way sub-process can pass an output variable value to parent process, if the sub-process run for 2-3 times, and the value may only be generated once. I am able to catch only empty values after the sub-process ends. I wish to send populated pv! values immediately to parent process, otherwise by the time sub-processes ends, the final process gets null values as the referencing parent process variable is never populated.


Thanks!
