Any simple way to change a missing value injecting another value from a variable?

Hi all

possibly a dummy question? I am not able to fix a missing value in a column with another value coming from another column of the same table and same row? Any hint? I would like to inject a value variable and not a most common or not a fixed one like suggested in "missing value" node.

Any way to let missing value node see variable other than knime.workspace?

Best

Andrea

I use column combiner to combine both columns. Since one of them is empty the result is what you need.
