Creating calculated fields in Tableau Prep is pretty straightforward. Editing them isn’t. The first time I wanted to edit a calculated field in the product I had a moment of hesitation.
After creating a calculated field in Tableau Prep you get a new column. However, if you want to edit that calculation you can’t simply right-click on the column header and edit.
This stumped me for a while, but I continued to search the product until I found that by opening the changes pane you get a list of any changes applied and if you right-click on a calculation you are given the option to edit.
From there you can make changes as usual.
