Error un hpsplit with levelization

[juanvg1972]

Hi 

I am using proc hpspit in order to create a decision tree. I am usin SAS/STAT in SAS 9.04.01M5P091317

This is my code:

proc hpsplit data = train nodestats=arbol;
    target baja / level=nominal;
    input cod_posicion educacion sexo / level=nominal;
    input edad ant salario eval / level = interval;
    /* Export information about variable importance */
    output importance=import;
    /* Export the model code so this can be used to score testing data */
    code file="/home/user1/pgmas/model_arbol3.sas";
    rules file="/home/user1/pgmas/fich/reglas3.txt";
run;

and when I execute, I gets an error:

ERROR: Levelization contains no levels!

But I have specified the level of each variable.

The same proc and options runs well with other datasets

Can anybody help me??

Sorry, there was a problem in my data, not in the proc.
