Hi. why when we change any name in our dataset and then import it to the RM, it can not read it?

[Deleted User]

when I change any thing in my dataset RM is not able to find that part.

Are you having any special characters in the name? Can you provide what name you were trying to change and the new name? I could try. There is a rename operator inside rapidminer that can be used to rename.

Hello @mbs

It would be helpful if you provide more information. What is that you are changing in the dataset? Is it attribute name or data? Are you trying to change that inside RapidMiner using edit data or outside RapidMiner and importing it again?

Please provide as much information as you can and any images that help us understand the issue. 

Thanks

When ever I change any attribute(column name) in my dataset  outside of the RM and then import it to the RM unfortunately RM is not able to understand it and suddenly this error show that: " your dataset doesent have this column.
"

For example the previous name was "risk" and the new one is " risk score". But I think RM  is not able to understand space character and also it is not able to understand capital or small letters. By the way the set rol part has a problem in the import part because half of the import part is read.

I am able to get all the data with different names when I import into RM.

Sorry unable to understand, in your image you did not connect the data and set role operator so it shows that red bulb. Also, once you import new data you need to remove previous retrieve and drag and drop new data to see the change.

Sorry, @mbs I cannot recreate your error. Everything working well for my data with same names. As I don't have your dataset my help is limited.

Thanks
