Notes
Field Dependency is a feature in Salesforce that allows fields to be dependent on each other, meaning the value of one field affects the available options in another field.
Field Dependency is often used to simplify data entry and improve data quality by reducing the number of options available to users based on the value of another field. For example, if there are two fields named "State" and "City", the options available in the "City" field can be restricted based on the value selected in the "State" field, ensuring that users can only select cities that are associated with the selected state.
