Cannot use any other data to run workflow from Rapid Miner Book

I would like to use the Similarity-based Content Recommendation process from the rapid miner book (http://rapidminerbook.com/index.php/chapter-downloads/chapter-9/, chapter 9.5.2.). It works fine with the provided .ioo, .md and .properties data, but when I load my own data (attributes are the same) into the repository, it doesn’t work although there is no error message.


I already convertet the original .ioo file into a new excel file (with the write excel operator) and added this excel file to the repository, which is also not working. I presume I am missing something while adding an excel file to the repository (I start with +add data and follow the import wizard). Does someone know where the problem could be? 


Thank you for your hints and help.

    The first step I would look at is why you can't seem to load your data. Try converting your XLSX file to a CSV and use the Read CSV operator. Sometimes in XLSX files there are wierd formating or encoding that can mess things up.

    Thank you for your reply. Unfortunately the import with CSV made things worse. But I tried the excel import with two different processes and it worked, so I conclued that the excel import must be ok. I searched for solutions within the process and was successful. I added two "nominal to text" operators after the first item preprocessing operator.
