This section describes new features in the transformations for dynamic mappings.
Effective in version 10.0, you can add dynamic ports to some transformations. You can also parameterize which input ports to link to ports from an upstream transformation. You can configure port selectors to reference multiple ports in transformation logic.
The transformations contain the following new tabs in the
Properties
view:
Group By
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.
Port Selector
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.
Run-time Linking
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.
