When creating a dataset in DV mode, it would be helpful to add a Union option, in addition to Join.
Hi @Bryan K - Have you checked out the functionality within Data Flows yet? If so, what about Data Flows does not address what you are trying to do?
Yes I am familiar with Data Flow and it does work well. Adding it to the Datasets would save an extra step, and save from creating additional datasets from the output of the Data Flow union. Additionally, you may need to account for the reload time/schedule of the dataset when scheduling a dataflow/sequence to run.
