In our Org, we are using Person Accounts; so Joe Smith can have preferences, for example he only wants red cars when renting.
There's a duplicate Person, Joseph Smith, who of course only wants red cars.
When we identify that Joe & Joseph are the same people, and merge them, we end up having two preferences that are the exact same.
What would be the best way to tackle this? Aside from going into each Persons and checking to see if they have duplicate preferences.
Will it be done through a trigger?
