Thank you for using a retail example in this video! Really glad this video is part of the L3 certification. I use this function all the time. It's basically the function that simulates the "remove duplicates" in Excel. It also helps me from having to delete entire lists and rebuild them. Without a doubt ISFIRSTOCCURANCE() is one of the best functions for data integration. Thanks for posting this great video!
