Whenever I have worked on similar projects in ended up being the customer's idea of what a "close approximation" was that made a possible duplicate. It was usually something like: same birth date same last name same city (optional) same state (optional)
Since there is not such a thing as a tried and true method for what a duplicate record is I believe you'll just need to do some manual work. My advise would be to ask your customer/boss for what the rules are. On Jul 11, 4:29 pm, Justin Stanczak <rizen...@gmail.com> wrote: > Yes, this is all very true.
