change tracking

[DesignGroup]

hello.
does change tracking fields track changes made in reffered rows (nested rows)?
if not, how is it possible to trigger an event in one table based on changes made in another table?

No, it does not. 

There are several ways to achieve updates in one table based on changes in another.  You use case will decide which approach is best.

As for how to force an update in another table, that is usually accomplished through actions.  Actions are executed either based on a Save performed OR by Automation - a Bot detects a data row has changed.

In both cases, you will eventually use what I call a "bridge" or "transition" action - action type = "execute an action on a set of rows".  This special action allows you to specify an action to execute against a set of rows in another table. See image for example
