Hello,
I am new to rapidminer. I would like to train a model using cross validation and test it later on subsets ( like female and male users and different regions subsets). I wonder how I can split the test set into subsets, which operators? and what to use for applying the model and getting it performance on those subsets?
Thanks,

use the 'Set Role' operator to do so. make for instance your user column 'label' and it will automatically create 'subsets' using this column.0

You can use the Cross Validation operator once you have a label and you will have different options for creating the subsets such as sequential, randomized, or batch (where you specify the subsets manually via another attribute).
