Contact table inner joins

Content

Hi All,

Could we create a report/filter for the contacts table with in contact?

For Eg:I have to retrieve the duplicate contacts in the system.some times first name,last name and mobile number are same but the email address is different.I need to retrieve all the contacts which are having the same mobile #,first name and last name.

Kindly suggest some ideas to do this.

 

Thanks,

Muthu
