# Trigger

## Business Rule

{% hint style="warning" %}
There is no need for you to manually create a Trigger (Business Rule). If you have more than one, you will make duplicate updates.
{% endhint %}

{% hint style="info" %}
Unifi will automatically create a Trigger (Business Rule) for the Process being integrated *(if one doesn't already exist)* when you run 'Build' either on the Integration or Message once your Create Message is configured.
{% endhint %}

In **native ServiceNow**, navigate to **System Definition > Busines Rules**. Find and navigate to the automatically generated Business Rule.

{% hint style="info" %}
The format of the name will be '\[S] Unifi ' + \<Table Name> + ' trigger rule'.
{% endhint %}
