While building a workbook you want every occurrence of the member value "N" in the discrete field Ship Mode to display as "Next-Day" in all views, but you must keep the underlying database value unchanged. Which Tableau Desktop action accomplishes this goal?
Build a calculated field that returns "Next-Day" when Ship Mode equals "N" and replace the original field in all views.
Define a custom data role that maps "N" to "Next-Day" and assign it to the field.
Open the field's Aliases dialog and set "N" to display as "Next-Day".
Rename the Ship Mode field to "Next-Day" in the Data pane.
Assigning an alias to a discrete field value changes only the label that Tableau shows in the view; the source data itself remains untouched. Renaming a field affects the field name, not individual member values. Creating a calculated field or mapping through a data role would require replacing the original field or editing the data source, neither of which is necessary when an alias can simply mask the displayed value.
