@BethBowers Yes, it was because there was bad data in PR1. First, I exported the PR1 to Excel and identified all the duplicate social security # people and deleted them in employee maintenance. Then I just had to keep deleting the bad records with DFDM and starting conversion over again until done. My problem was the client NEVER terminated anyone so there were people that hadn't worked since 2001. Also this client has an import to bring in PR employee records so that caused some issues. Luckily, none of the bad records were remotely current, so no history at all. Next time I will request my client get rid of people that haven't worked for 10 years!
