Use a single dataflow table to merge data with multiple fields?
I have a single Employee dataflow table in my new dataset. Within the dataset I have other tables I've brought in that need to look up employee information in that table based on a unique employee ID field. When merging data, should I just use that same Employee table to merge with the various employee IDs? Or should I bring in unique instances of the Employee table for each of those employee ID fields to lookup?
