Example 3: Lookup
This example builds on the previous example. A transformation is added to the data flow using the SalesPersonID from each aggregate record to retrieve the first and last name of the salesperson. The sales person name is appended to the aggregate record.

Open the Example3 package and switch to the Data Flow designer.
Delete the data flow output from the Sum Amounts aggregate to the Sales Order Destination by right-clicking on it and selecting Delete from the context menu.

Click on the Sum Amounts item. Drag the data flow output arrow to the Lookup Sales Person transformation.
Double-click the Lookup Sales Person transformation to launch the Lookup Transformation Editor dialog shown in the following figure.
