Contact Deduplication

(0) ShareShare
ReportReport
Posted on by 141

Hello Community,

 

I’m looking to solve a contact deduplication issue for a customer.

 

There are about 1 million contact records (a massive number of duplicates). They imported spreadsheets into the system over the years without any guidance or best practice on how not to create duplicates.

 

I have set up Duplicate Detection Rules on the Contact

  1. Go to Settings → Data Management → Duplicate Detection Rules.
  2. Create rules for:
    • Contact: Email, Full Name + Mobile, Full Name

 

How best can I approach these issues - Data deduplication, matching logic, automation, auditing, and preventive controls.

 

The customer does not allow any third party tool (XRM Toolbox etc) on there tenant.

 

I would like to automate (Automated Merge) this process and be able to count and log the deletions. All using low code. I’m not a developer.

 

I look forward to all the support.

 

Kind regards,

 

Chi
