You can now achieve a duplicate detection rule by defining the lookup as an alternate key. You can create an alternate key by following the below steps
- To define the alternate keys, go to Go to Settings> Customizations
- Choose Customize the System–>Components ->Entities –> Entity–>Keys. Choose New.
3. On the form, fill in the required fields (Display Name and Name) and then choose and add the fields to the key. Save the key. In the example shown here, we used the ParentId field in the alternate key definition.
