Return Data Table Argument if error occurs


I have a question for returning argument in Main and Sub flows.

I created a totaldt (in/out data table argument) variable in sub flow. I think the totaldt should not be passes to Main flow when error occurs. But when i debug the script, totaldt returned to Main flow, you can see below yellow highlighted lines for reference.


I also attached the files here. Thanks in advance for your help!!! (23.5 KB)


I suppose it’s caused the argument is passed by reference.
If you want to abort it, check isolate option in Invoke Workflow file activity. It will behave like passing by value.
