Duplicate Detection Rule not saving

(0) ShareShare

Posted on by 8

I have a lot of duplicate "To-Do" activity types in my environment and so I am want to create a duplicate detection rule.  However, when doing this I keep getting an error that says:

    Hello, 

    The message is related with the length of the matchcode created based on your criteria. It's exceeding the limit:

    When you create a duplicate detection rule, a matchcode is created for every record in the matching record type for that rule. 

    Please check the official documentation for more details: https://docs.microsoft.com/en-us/power-platform/admin/detect-duplicate-data 

    Hope this helps you.

    Please mark the answer as verified if helpful. That will help others in future.
