Step 5. Create and Configure a Run-time Link

Create a run-time link to the Write transformation and configure a link policy to establish and resolve links by port names at run time.
  1. Press Ctrl and drag the All Ports group from the Aggregator transformation to the All Ports group of the Write transformation.
    The
    Run-time Linking
     dialog box appears.
  2. Verify that
    Link Policy
     in the Link Properties area is selected to automatically link ports by name at run time.
    The Link Properties area of the Run-time Linking dialog box has two options Parameter and Link Policy to configure the run-time link. The Link Policy option is selected.
  3. Click
    OK
    .
    The Developer tool creates a run-time link between the Aggregator transformation and the Write transformation.
    The mapping contains two Read transformation for CUSTOMER and ORDERS tables. The mapping also contains a Joiner, an Aggregator, and a Write transformation. The mapping shows the ports in each transformation and the links between the transformations. A run-time link exists between the Aggregator and Write transformations.
