I am facing one challenge in KNIME, kindly suggest me which node is best to solve this problem:
I have 4 columns name as A, B, C, D and need to create column E where the name of columns would be there based on values in A,B,C,D. Example excel attached Example.xlsx (8.8 KB)
Or if you are creating the new column with some math/string formula node you could have the Rule Engine node create a flow variable for you that gives the new column name.
