Hi Everyone,

 

When running decision tree I get the error: Tool #290: An unknown error occurred in II_Close. Do you know what can cause this type of error?

Need to check your data types are correct, I get this when I forget to clean them up.

As the answerer below notes, it is probably a data consistency issue.  I was getting the same error, and I inserted a select tool and changed all my numeric variables to either fixed decimal of the same size or integer.  This immediately fixed the problem.
