Run bulk system jobs to detect duplicate records


Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2013, Dynamics CRM 2015, Dynamics CRM Online, Dynamics CRM 2016

To maintain the integrity of system data, you should check for duplicates regularly to make sure that users don’t inadvertently create duplicate contacts, accounts, leads, or other types of records.

The Check for Duplicates wizard helps you set up a bulk “job” that finds and cleans up duplicate records. You can schedule the job to run daily, and you can receive an email confirmation when the job finishes.


If you haven’t already done so, create and publish duplicate detection rules, and turn duplicate detection on before you run the wizard. More information:   Set up duplicate detection rules to keep your data clean

  1. Go to Settings > Data Management.

  2. Click Duplicate Detection Jobs.

  3. Click New, or select the name of the duplicate detection job you want to run.

    You’ll see the Duplicate Detection wizard, which helps you create a job to check for duplicates.

  4. Click Next.

  5. In the Look for drop-down list, select the record type that you want to check for duplicates.


    What you see in this list depends on which duplicate detection rules are published. More information:  Set up duplicate detection rules to keep your data clean

  6. In the Use Saved View drop-down list, select a view if you want to limit the records searched to records in that view. For example, select Active Accounts. When you select a view, Dynamics 365 adds the criteria to search on.

  7. To further limit the records searched, click Select and then enter the criteria you want.

  9. Accept the default name for the job, or type a different name.

  10. Enter the start time for the job, and enter how often to run the job in days. (To run the job daily, type 1.)

  11. If you want to receive an email confirmation when the job is completed, select the Email options check box. Enter an additional email address, if desired.

  12. Click Next, and then click Submit.
