What reason can be given for a Delegated Administrator being unable to edit the Created Date field on an Account?

The reason for a Delegated Administrator being unable to edit the Created Date field on an Account is that this field is classified as a System Audit field. System Audit fields, including Created Date, are designed to automatically track the creation and modification of records within the system. Because they serve as important timestamps for record management and system integrity, these fields are read-only for existing records.

This restriction ensures that the audit trail is preserved and that the integrity of the data remains intact, as allowing modifications could lead to confusion or manipulation of data regarding when records were created. Other mechanisms in place, such as permissions, page layouts, and field-level security, control access and behavior of fields, but they do not apply to audit fields in the same manner as other data fields.
