Dear Rapidminer Community
I have a strange problem with "append" I hope you can help me with!
I have 7 datasets with the same attributes which I want to append but I am only able to "append" 5 of them. I have tried now everything to get the same attribute names but it still doesn't work. I have even copied the attribute names from a working ("appendable") dataset and implemented it in the table which can't be appended. Still doesnt work. Furthermore, I have made sure that there are everywhere the same datatypes. And I have restarted my computer just to make sure this wouldn't be the problem..
Is there anything else I can check? The error message I get is: "The attributes of the example set have to have the same attributes". But no further information where the problem ist.
I am quite clueless what else I could do..
