We can't seem to get it to work using any of the available transformers, nor any of the help we've searched for online. We just end up with either the data in the output table staying the same, or an error in the transformation. We are using a standard file GDB in ArcMap with a FC containing about 10 million records, and we want to replace about 200,000 of those records with updated info that is located in another FC in the GDB (based on a common field (county)).
Is there a way to do this??
