A superseded document is one that has been officially replaced by a newer, more current version. When a document is updated, the application automatically shifts the old version from 'Effective' to 'Superseded' under the 'Retirement Reason' column, the moment the new version is approved and published.
The obsolete status is used for documents that have been permanently retired from use. Even though an obsoleted document is no longer active, it remains stored within the account. It is essentially locked in a 'read-only' state, hidden from daily users but available for auditors who may need to verify what the standards were during a specific historical period.
