Hi @sofia75,

Use De-pivot operator :

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.

Regards,

Lionel
