I have a KNIME query about looping.
I have a column that has been split out 'onetomany'. I then have another column in the table that I would like to multiply all of these new columns by, without having 30 'Math Formula' nodes!
Things that I have tried:
1 - Using 'column list start loop' and 'Loop End (column append)' with a math formula node inbetween (with flow variable ports).
2 - Using a java snippet (with flow variable ports).
3 - Using 'splitter' and 'cell replacer' (with flow variable ports).
None of these has worked so far.
If you have a simple method, please enlighten me. If you want more information about what I have already tried, let me know.
(The dataset is very large, so writing it to csv won't work either.)
