Introduction
Many companies want to add extra data to existing tables in Dynamics 365 Business Central. For example, they might want to track something unique about each of their customers in a field that doesn't currently exist in the application. Developers can help address these requests by creating extensions to tables.
In Business Central, you can't just change existing tables by modifying some source code. If you want to add extra fields to an existing table, or only want to modify some properties, you need to use table extensions.
In this module, you'll learn how to create a TableExtension object and compare some properties with the Table object properties.
