Reusable transformations can be used in multiple mappings. When you needs to incorporate this transformation into mapping, you adds an instance of it to mapping. Later if you changes the definition of the transformation, all instances of it inherit the changes. Since the instance of reusable transformation is a pointer to that transformation, you can change the transformation in the transformation developer; its instances automatically reflect these changes.
