Rule Engine on Multi Columns

Hi Team,

Is there a possibility to run a Rule for multiple columns?
I just saw your answer for other related forum question, but this only applies to numbers:

Rule Engine on Multiple Columns - KNIME Analytics Platform - KNIME Community Forum

What about if I have multiple columns where I just want to transform the value of the record from β€˜(blank)’ to just empty for multiple columns?

Is there a way to do that with just one node?

Hi @MarcEM,

You can use the β€œString Manipulation (Multi Column)” node with replace($$CURRENTCOLUMN$$, "(blank)", "") for that :slight_smile:

Best, Lukas


Hi Lukas,

Thank you!

This worked out.
