Reusable Transformation Instances and Inherited Changes
Reusable Transformation Instances and Inherited Changes
When you add a reusable transformation to a mapping or mapplet, you add an instance of the transformation. The definition of the transformation still exists outside the mapping or mapplet, while an instance of the transformation appears within the mapping or mapplet.
When you change the transformation, instances of the transformation reflect these changes. Instead of updating the same transformation in every mapping that uses it, you can update the reusable transformation one time, and all instances of the transformation inherit the change. Instances inherit changes to ports, expressions, properties, and the name of the transformation.
