Effective in version 10.1.1, when you create a Write transformation from an existing transformation in a mapping, you can specify the type of link for the input ports of the Write transformation.
You can link ports by name. Also, in a dynamic mapping, you can link ports by name, create a dynamic port based on a mapping flow, or link ports at run time based on a link policy.
For more information, see the "Write Transformation" chapter in the
Informatica 10.1.1 Developer Transformation Guide.
