If you enable ADP and you specify a transformation list, the transformation list is embedded with the automatic, system-generated transformations. The transformation list is executed before the automatic transformations.
If you enable ADP and do not specify a transformation list, only the automatic transformations are embedded in the model.
If ADP is disabled (the default) and you specify a transformation list, your custom transformations are embedded in the model. No automatic transformations are performed.
If ADP is disabled (the default) and you do not specify a transformation list, no transformations will be embedded in the model. You will have to transform the training, test, and scoring data sets yourself if necessary. You must take care to apply the same transformations to each data set.
