I've spent an hour looking for an answer but haven't found one. So, here's the question:
I want to rename the value 'null' (meaning missing data') across several dimensions as "No Information". I can do this one by one as an alias - but I need to do it for 50+ dimensions.
Also, Ideally I'd like the ability to do it to a data source published on Tableau Server...but will settle for a solution to change in the data source before publishing. below is an example of a portion of a dashboard....I'd like the 'null' to show up as "No Information".
Currently, there is no way to do this easily within Tableau without editing each dimension or creating a calculated field. This might be a good one for the Ideas section! Otherwise I would recommend doing this within your datasource.
