How do you prevent a data field from being modified when using the Select Tool?

The correct method to prevent a data field from being modified when using the Select Tool is achieved by unchecking the box next to the field. When you uncheck the box for a particular field within the Select Tool, you are instructing Alteryx to exclude that field from further processing or modifications in the workflow. This means the field will remain unchanged as it passes through the workflow without any alterations, allowing you to preserve the original data integrity.

The other methods mentioned do not directly prevent modifications in the same way. For example, locking a field, while it might seem like a viable option, usually pertains to preventing changes in different contexts, such as in the user interface rather than specifically within the Select Tool. Setting a filter is meant for limiting the data that is processed based on certain criteria, rather than safeguarding against modifications to a field. Renaming a field does not prevent modifications; it simply changes the label by which that field is referenced in the workflow.
