# Trigger

## Business Rule Fields

{% hint style="warning" %}
When configuring a Trigger (Business Rule) on a table to be integrated, make sure one doesn’t exist already. If you have more than one, you will make duplicate updates.
{% endhint %}

In the **native ServiceNow** window, navigate to **System Definition > Business Rules**. Click **New**.

The Business Rule fields to be configured are as follows:
