# Merge Duplicates
The Merge Duplicates button allows CRM users to instantly merge multiple selected records directly from any Dynamics 365 grid, and duplicate detection runs.
This gives business users real-time control over data cleanup while DeDupeD ensures that relationships, history, and integrity are preserved.
**What this feature solves**
Native Dynamics 365 allows users to merge only one duplicate pair at a time.
DeDupeD’s Merge Duplicates button removes all those limitations:
You can now:
* Select up to 10 records
* Merge them even if they were not flagged as duplicates
* Control which record becomes the Master
* Control field-level data survival
* Preserve all relationships, activities, files, and history
All in one controlled workflow.
How to Merge Records Using “Merge Duplicates”
### **Step 1 – Select the records**
Go to any configured entity view (Contacts, Accounts, Leads, etc.)\
Select all records you want to merge using the checkboxes.
Example:You select 5 Contact records.
### **Step 2 – Click “Merge Duplicates”**
From the command bar, click: Merge Duplicates
DeDupeD will detect that:
“These records were selected manually and may not be identified as duplicates…”
Click **Yes** to proceed.
This gives users full freedom to clean data even when native duplicate rules are incomplete.
### Step 3 – Review & Select the Master Record
The DeDupeD merge screen opens.
You will see:
* One Suggested Master
* All other selected records displayed side-by-side
{% hint style="info" %}
**Note:** If the master deciding rules are applied for the entity, the master will be suggested based on the master deciding rule score.
{% endhint %}
Choose the record that should become the Master — this will be the surviving CRM record.
The Master will keep:
* All relationships
* All activities
* All history
* All connected records
### **Step 4 – Choose which field values to keep**
For every field (Name, Email, Address, Phone, etc.) you can:
* Select values from different records
* Or use **“Select all fields”** from one record
This gives you field-level control, which native CRM does not provide.
### **Step 5 – Finish the merge**
Click **Finish**.
DeDupeD shows a confirmation:
The selected relationships will be merged into the master record and duplicates will be deactivated.
Click **Continue**.
The merge begins.
### **Step 6 – Background merge of relationships**
You will see a message:
“Related records are being merged in the background…”
DeDupeD now:
* Reassigns activities
* Moves opportunities, cases, quotes, etc.
* Reconnects emails, notes, files
* Deactivates duplicate records
All without breaking data.
### **Step 7 – Verify the result**
Open any of the duplicate records.
You will see:
“This record has been merged with \[Master Record]”
The duplicate is now:
* Inactive
* Fully merged
* All its data moved to the master
### **Step 8 – Audit & reporting**
Every merge is logged in DeDupeD Job Runs.
You can see:
* How many records were processed
* How many duplicates were merged
* Which master record was created
* When it happened
* Who executed it
This gives IT and Compliance teams full visibility.
