I have an existing workbook. If I try to edit any calculated field, it shows 'Edit Copy' and if I select 'Edit Copy', it creates a copy to edit.
Why is it like that ? How was it achieved ?
This happens if the workbook is built off a published data source. Tableau is restricting users from editing original calculations hence it creates a copy of the same to edit.

Hope this helps.
