How to " tell" RM what to use for training/ testing

LG222PS

Dear Miners,
Please help me to get the hang of this.
I have a desicion tree model with a set of data that has about 60 000 rowas of data with the lable attribute and 15 000 without. I assumed/ wanted the data with the lable attribute to be the training data and the rows with missing lable attribute should be the test values ( wich I want to export at the end for external validation)
Now my export only has 5900 rows of data and it seems not to use the " empty" rows for test, but replace missing values with mean value per default option and split the whole data into test and training set. 
I am wondering how to fix this issue, without having to disassembke the entire design ( which would be painfull, since I already incorporated the modle outcome in my thesis draft)
Could you please help me?
Kind regards
A data science newbie

Hello @LG222PS

Did you filter the data using "Filter Example" operator with a Condition Class "no_missing_lables".? This will separate the data with missing labels and no-missing labels. You can use the labeled data from training and unlabeled for testing. Below is the XML code and I also attached dataset with missing labels for you to test this code. To do this, you need to download dataset attached. Now in the XML window of rapidminer process copy the below code and paste it, then click on the green tick mark. Now you will see Read CSV operator in process, in the parameter options, point CSV file parameters to the data set you downloaded. If you are unable to find XML window, go to view --> Show Panel --> XML.

Filter example operator output ports, "exa" is the output port related to filtered values (in our case no missing labels), "unm" are unmatched values, in our case data with missing labels.
