Missing value

[Linda97]

How can I replace missing value of a column with value of other column using a prepare ?

Hi @Linda97,

You can use a formula step with a coalesce function as shown below. 

I used coalesce(null, "string") where the column with the empty cells is null and the column with the values you want to replace the empty cells with is "string".

Please let us know if you have any questions.

Thanks!
