Not so much a screen. Just populate a few forms with information from that specific record. We found a way where we just look in each phone number field for the record looking for a match. This is probably "expensive" in terms of overheard on the server, but it works. Also have had no complaints of it being slow. The possibility of different customers is real but does happen. For that we have a checkbox for duplicate customers. We simply contrain out any records marked duplicate to get rid of the problem. Seems to be working so far.
