Universal Requiredness for Salesforce Fields

A.

Universal requiredness is a feature in Salesforce that allows an administrator to make a field required for all users, regardless of their profile or page layout. This means that the user cannot save a record unless they fill in that field.

Out of the given options, the correct answer is A. Lookup fields cannot have universal requiredness. A lookup field is a type of field in Salesforce that allows you to create a relationship between two objects. For example, you might have a custom object called "Orders" and a standard object called "Accounts." You could create a lookup field on the "Orders" object that references the "Accounts" object. This allows you to associate an order with an account.

The reason lookup fields cannot be made universally required is because they rely on another object being present in order to be completed. For example, if you make a lookup field to the "Accounts" object required, it would mean that a user would not be able to save an order without also having an account to associate with it. This can be problematic because users may not always have all the information they need to fill in both the order and the account at the same time.

On the other hand, text, email, and number fields can be made universally required. These are all standalone fields that do not depend on other objects or fields to be completed. Therefore, making them required for all users does not create any issues with data integrity or usability.
