"exceeds maximum number of levels cutoff" (well under 512)

[Mike90]

I am getting this message in the score report of a decision tree model.  Three variables are not being used for this reason.  These variable have between 150 and 250 levels.  I can drop a lot of rare levels, but I need to know what the cutoff is, and if it can be changed.  I read there's a 512 level cutoff for logistic regression.

Googling for this exact error message returns 2 results, neither of which is about resolving this problem.

Thanks.

Post what you've tried so we don't suggest those. 

So, we can assume you've set/changed the maximum levels in the project settings?

I went through the settings, and I don't see where to set this.

I see Options -> Preferences, and there are options to the left of any selected node. .

2 irrelevant Google matches for the exact error message isn't a lot of help.

I did try increasing exhaustive candidate splits on the decision tree to 15,000.

Project Macro Variables?

EM_TRAIN_LEVELS?

I'm not sure what you mean by 2 irrelevant results, searching "sas maximum levels 512" returned a lot of results, not all relevant as usual. The first one is the note above which includes:
