Hey, everybody, first of all, thank you very much for all the help. I’m a beginner at KNIME so there’s a lot of things I don’t handle yet.
First of all, I have a dataset that I’ve divided in two, according to some columns that I work separately
This is what I do, but with a Ungroup, I lose the row id and I don’t know how to put the data back together
I’d appreciate your help. Thank you very much in advance
