The administrator at AW Consulting has created a custom picklist field. Business users have requested that it be a text field. The administrator attempts to change the field type but, is unable to because it is referenced by other functionalities. Which functionality is preventing the field type from being changed?
A. Formula fields
B. Record types
C. Visualforce
D. JavaScript
A. Formula fields
Explanation:
Formula fields are types of fields that calculate a value based on an expression or formula that references other fields or constants. Formula fields prevent administrators from changing their field type once they are created because they may be referenced by other functionalities such as reports, validation rules, workflow rules, etc., that depend on their data type and value. If a formula field is referenced by other functionalities, then changing its field type may cause errors or unexpected results.
