If the default transforms do not meet your needs, you can also create and add custom transformations to a transformation script on the Editor tab of the Transform page.
Creating a custom transformation
You can create a custom transformation by writing custom Groovy code in the Transformation Editor. After you save the custom transformation, it is added as one individual execution step to the transformation script.
Writing custom transform code
Transformations can contain attributes and records from your project data set as variables, and can create new attributes to hold the transformed values.
Exception handling and debugging
These topics describe exception handling in Transform and show how to debug individual transformations.
