Dear all ,
I have tried using the (2) suggested methods of changing variable from nominal to interval and also to add %let EM_TRAIN_MAXLEVELS=n; to project start code.
My dataset doesnt allow me to choose interval and i have placed the code in the Code utility .
Currently, the flow is SAS Code -> Dataset -> Decision tree
In my dataset i have user_id , item_id , results cols .
results is 1 for followed , -1 for not following
I wanna based the decision tree on 2 leave nodes ( followed ) or (not followed)

This error does not necessarily mean that there is a problem. If you encounter this error and do not suspect a problem with your data, then you can eliminate this message in two ways.
N equals the maximum number of levels that you want to allow.
Use whichever method you judge to be statistically appropriate for your analysis.
