Hi Guys,

Hope all of you are doing good.

Actually I have a one issue. is that, when we open up any module record like Leads Record, then there are options are giving like Edit, Duplicates, Delete, Find Duplicates and etc.

Now when I click on Find Duplicate Option, it is giving some options like Office Phone, Home Phone etc. Now I need to add some other fields like First Name, Last Name and some other custom fields. So can anyone help me and tell me how to do this task. How to add more fields in Find Duplicate Section to find duplicates.

I will be thankful to you.

Any Help Will be Appreciated.
