How can I bring together data that I have previously divided up ?

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

Hi,
You can use the RowID node to add the current RowID as a normal column. Then later, after merging, you can use the same node to restore the RowID from that column.
Kind regards,
Alexander
