What should you use to extract the data set?
When you need to extract a data set that is the result of a union between two tables, you should use physical tables that use multiple table extracts. Logical tables represent a more abstract level, while physical tables deal with the actual storage and structure of the data. To correctly extract data from a union of two tables, you need to work with the physical tables involved in this union, utilizing multiple table extracts to handle the combination properly.
