# Duplicate detection - When does it happen?

## How Does Duplicate Detection Work in Delpha?

Duplicate detection in Delpha is a **scheduled process** that runs **every 12 hours**, automatically scanning your Salesforce org to identify potential duplicate records.

This article explains how the detection works, what triggers it, and how to pause or stop it if needed.

## What Triggers a Duplicate Detection?

Delpha scans for duplicates under the following conditions:

* ✅ **New records** created in Salesforce **(excluding those flagged as D Do Not Process = True)**
* ✅ **Modified records**: If **any field** listed in the *Fields section* of the **Delpha Duplicate Settings** is updated, the record is automatically re-evaluated.

This ensures that even long-existing records are reconsidered when relevant data changes.

## When Does It Run?

* **Frequency:** Every **12 hours**
* **Scope:** Applies to **Contacts, Accounts, Leads**, and any object configured in your Delpha Duplicate Setup

## How to Disable Duplicate Detection

You can temporarily or permanently stop the detection process:

**1. Deactivate the Duplicate Use Case**

* Go to **Delpha Duplicate Settings**
* Turn **off** the Duplicate detection use case for the relevant object

**2. Set Detection Frequency to ‘Never’**

* Open the **Delpha Setup app**
* Navigate to **Tab: Delpha Configuration → Section: Duplicates**
* In the **frequency dropdown**, select **‘Never’**
