You can create transformations using the following Designer tools:
Mapping Designer.
Create transformations that connect sources to targets. Transformations in a mapping cannot be used in other mappings unless you configure them to be reusable.
Transformation Developer.
Create individual transformations, called reusable transformations, that use in multiple mappings.
Mapplet Designer.
Create and configure a set of transformations, called mapplets, that you use in multiple mappings.
Use the same process to create a transformation in the Mapping Designer, Transformation Developer, and Mapplet Designer.
To create a transformation:
Open the appropriate Designer tool.
In the Mapping Designer, open or create a Mapping. In the Mapplet Designer, open or create a Mapplet.
Click Transformation > Create and select the type of transformation you want to create
.
Drag across the portion of the mapping where you want to place the transformation.
The new transformation appears in the workspace. Next, you need to configure the transformation by adding any new ports to it and setting other properties.
