Consider that you have created a visual analysis in the Dataiku Lab. In the Script tab, you have added steps creating new columns in the dataset. If you save the script, return to the Flow and open the same dataset, will you find these newly$-$created columns?

a$.$ No$.$ The script would first need to be deployed to the Flow to find these columns.

b$.$ Yes. It is the same dataset, and so the columns must be there.
