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.

1. Use the options on the Add Data pane to configure the data set. For example, change the default name, or include and exclude columns.
2. To add another data set to your flow, click Add a step (+), and select Add Data.
   If matching columns are found in data sets, a Join step is automatically added to enable you to define the relationship between the data sets. For example, you might want to combine rows from two data sets where the CustomerID in the first data set matches the CustomerID in the second data set.
3. If you don't get a Join step automatically, click Add a step (+), and select Join.
   To complete the join, on the data flow diagram click the circle on the dotted line between the data source step and the Join step. Then use the Join pane to configure the relationship between the data sets
4. Click your data set step again and use the options on the Add Data pane to configure the data set.
