You create regions when developing in PowerApps. Adopting a naming conventions for all regions is one good way to stay organized and help other people working on the app. As an example a region’s name could be SchoolYearDD. The name of the region lets you know that it is a dropdown region (DD), and from the dropdown you are able to select a school year (SchoolYear). Here’s a list of some regions and naming conventions I have come up with.
Feel free to use this or come up with your own. Having a naming convention set from the beginning allows everyone to work with the same method, and allows another team member easily see what you are doing. The benefits extend to reporting and integration work as well.
