A Delegated Administrator at Universal Containers cannot edit the Created Date field for the Account record. What reason should the System Administrator give for why this is occurring?

Even if the user has Edit permissions on the Account object, system audit fields like Created Date remain uneditable at a fundamental system level.

While a field can be read-only on a page layout, system audit fields are read-only regardless of page layout settings, which cannot override this system-level restriction.

The Created Date field is a system audit field automatically populated by Salesforce when a record is created. It is inherently read-only for all users on existing records to maintain data integrity and an unchangeable historical record.

Field-Level Security (FLS) can restrict field access, but the Created Date field is intrinsically read-only as a system audit field, making FLS irrelevant for enabling edit access on existing records.
