I want to copy data from one column into another column of same dataset. What operator to use

I don't want to create unnecessary fields and then again have to remove them using select attribute. Have checked Generate Copy but that is alo creating a new column. Am not able to copy the data from one column to another

Hi,

you can use Generate Attributes and just enter the name of the attribute you're overwriting. This won't create a new attribute but work on the existing one.
