I was reading an article by appsheet help, and there was this article:

Changing Data from a Workflow Rule or Scheduled Report

How to change data in your app on a schedule or when some event happens.

It’s about invoking an action on another table based on date from current table. So i built the app just to find out what i already know, you can’t have a workflow rule to change data on another table.
Or can we?

I’m a bit confused here
