Hi 
I have a file where in many cases one server host several applications. In my file, I have only one line with the server's name and the applications names seraparate by ",". Exemple below:

VMPRDSUUGSQL40 Toto, Tata,Titi

I would need to have a line by application (one server=one application), like this:

VMPRDSUUGSQL40 Toto
VMPRDSUUGSQL40 Tata
VMPRDSUUGSQL40 Titi

How can I have this please?

Thank you very much,

Regards

    Hi @sofia75,

    Use De-pivot operator :

    <?xml version="1.0" encoding="UTF-8"?><process version="9.2.000-BETA2">
      <context>
        <input/>
        <output/>

            <parameter key="create_nominal_index" value="false"/>

          </operator>
          <connect from_op="Create ExampleSet" from_port="output" to_op="De-Pivot" to_port="example set input"/>

    Thank you very much Lionel. I am completly new in RapidMiner, my file is an Excel. I tried your code in "Excute Script" operator and then " De-pivot operator" and I get an error (line 7) and try several changes but I did not could fix error. Then I put De-pivot operator" first and Excute Script" operator (as bewlow) and I have this error "supply a value for index_attribute"...what attribute can I put?

    Can you please tell me what wrong ?

    Thank you,

    Regards,

    Hi @sofia75,

    You can call the index attribute "id" and remove it later with Select Attributes operator.
