The Aggregator transformation, the Rank transformation, and the Sorter transformation require that you configure groups of ports. You can now configure the groups on a

Group By

tab. You can define groups by selecting ports or you can configure parameters that contain port lists. The

Group By

tab provides flexibility when you configure the transformations with generated ports.

You can reference multiple ports in transformation logic. Define a port selector, which is an ordered list of ports. You can use reference port selectors in dynamic expressions, join conditions, or lookup conditions. When you define a port selector, you can include or exclude transformation ports based on the port name, the port type, or a pattern of text characters.

When you configure transformations in a dynamic mapping, you can set parameters or link policies that determine which ports to link between transformations. Configure run-time linking to link dynamic ports to static ports. You can configure a link policy to link ports by name. You can configure an InputLinkSet parameter to specify the names of the of ports to link at run time.
