Understanding Functional Fields in ServiceNow: A Comprehensive Guide

Functional fields are a powerful feature in ServiceNow that can simplify calculations and enhance data management. In this article, we’ll explore what functional fields are, how to create and configure them, their limitations, and alternatives. Whether you’re a ServiceNow developer or an admin, this guide will help you understand the practical applications of functional fields and how to use them effectively.

What Are Functional Fields?

A functional field in ServiceNow is a field type used to store calculated values based on other fields within the same table or related tables. These fields are particularly useful for automating calculations and reducing manual effort.

Example Use Case:

Imagine you need to calculate the total cost of an asset by summing its purchase price and maintenance cost. Instead of manually performing this calculation, you can create a functional field called Total Cost that automatically computes the sum of these two fields.
