Why does my Rule engine (Dictionary) node not work for me?

Hey all,

I try to solve an Alteryx Challenge (381) in KNIME.

Therefore I would like tu use the Rule-Engine Dictionary node.

However, as you can see it does not work for every row. I would have expected that the rows, where the rule does not hold, would be filled with nulls.

Can anyone please explain me my mistake?

Thank you very much

Hi @Robinvm

Alteryx :thinking:
Maybe it has something to do witjh this (from the Help-text Rule-Engine-Dictionary node)

If a rule matches, its outcome value is added into a new column. The first matching rule in order of definition determines the outcome.

thank you, you were right!

Rules were applied, that shouldnt be applied there. I looped now through the rules and it worked. :slight_smile:

Thank you
