When I go to Data Management and select Duplicate Management, I get the following message: "Luminate Online Duplicate Management is performed exclusively in your CRM. For details, refer to the Duplicate or Merging topics in your CRM help."
How am I supposed to manage duplicates in Luminate Online?
You are getting this message because your Luminate instance is integrated with a CRM. Duplicates should always be managed in your CRM as a best practice, so this feature is disabled as long as you are integrated.
