"How duplicate lines (have one server for one applications)?"

sofia75

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 :

      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

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,

Hi @sofia75,

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