ServiceNow Custom Tables 101: What You Need To Know

When I first started with ServiceNow 10 years ago, I made an embarrassing mistake with Custom Tables! I managed to prevent it from becoming a bigger issue, but with a better understanding of the nuances behind Custom Tables, I could have avoided the situation entirely.

In my latest video, I share my mistake in detail and provide a comprehensive overview of ServiceNow Custom Tables. I'll walk you through step-by-step how to use them correctly and avoid potential problems.

So, buckle up, and prepare to laugh at my past misfortune as you learn crucial information that will help assure your success when it comes to ServiceNow Custom Tables!

A few other things to mention:

1. Be aware of field inheritance that occurs when you create a custom table that extends another table. So example, when creating a custom table and you elect to extend from the Task table, your new table starts out with those required fields (as shown in the video), plus all Task fields. This is because your new table is considered a "child" to the Task "parent" table. More documentation about this located here: https://docs.servicenow.com/csh?topicname=table-extension-and-classes.html&version=latest
2. There are other types of tables that are exempt that I forgot to mention in the video and they are: Many to Many, Remote, Archive, Rotated Table Shards, and Document tables. More information can be found in the "Custom Table Guide" and page 3.
