Adding fields to base application tables

It's one thing to create brand new tables in order to track new information that doesn't exist in Business Central, but what if you just need to track a few additional pieces of data for an entity that is already part of the base application?

This recipe is going to show you how you can add a new field to the Customer table.

Some might refer to this process as customizing Business Central, but I'll be referring to it as extending the Business Central application.
