Exercise - Apply table permissions
The purpose of this hands-on lab is to set up table permissions to help secure access to Microsoft Dataverse table rows.
The exercises work best when you have sample data to work with. Depending on the environment that you're working with, you might want to install some sample data to assist with the exercises. Microsoft Power Platform allows you to add sample data as needed. If the environment that you're working in doesn't have sample data installed, follow the steps in the Add or remove sample data documentation to install the sample data into your environment.
