I see a edit button in the Annual Revenue property of Contacts. Why do you allow the user to change the data-type of that particular default property?
Why we can able to edit only the Annual Revenue property in Contacts among all the default properties?
Thank you for your patience on this. The 'Annual Revenue property was made editable since customers use that property in different ways. Some keep the field a single line text (allowing any value), while others change the field type to number (for a specific numerical value) or enumeration (to limit values to a set of options).
