Add Data in a Data Flow
When you create a new data flow and select a data set, you'll see a step with the name of your data set. You can add additional data from multiple data sources to your data flow.
Use the Add Data step in the data flow editor. If you've
created a new data flow project, your data set will be selected.
Note: Oracle Essbase and EPM Cloud data sets cannot be used in
the Add Data step as inputs to Data Flows.
