On Calling Two rules simultaneously in Process Model

To execute two activities in a process you use a AND node. See https://docs.appian.com/suite/help/21.1/AND_Node.html

Out of curiosity, what do you want to achieve?

Thank you Stefan.

I want to call two integrations and their outputs are independent of each other but want to call them simultaneously in PM.

Thanks

Faisal

OK. If there is no real need to run these in parallel I would not do it. And by need, I mean a business need. In Appian you typically do not do this kind of technical optimizations as you would do in other programming languages.
