You can use the approach described by @candby  where you would need to do a data step for each data partition being passed through (e.g. Train, Validate, Test) but those changes would not be reflected in the resulting score code.  It might be easier to just add a line to the Score code section of a SAS Code node such as the following:    MyNewVar = _NODE_;   The new variable MYNEWVAR will contain the value of _NODE_ in every resulting data set that is passed through the modeling node and/or scored by score code from a subsequent Score node.  Admittedly, you are not renaming the variable but still can accomplish the desired outcome.    Hope this helps!

Thanks for the input, Reeza   I tried using a decision tree to consolidate the levels. It worked for the variables seperately and grouped the levels. But then I cannot figure out how to get the 5 different consolidated trees into the data again?  The outputs from the separate decision trees are just _NODE_ for the new variables derived. So can I change the name, so they wont have the same name?     ... View more
