Special Access Rules

Knowledge must be enabled in your org. This object respects field, entity, and record-level security. You must have at least “Read” permission on the article type or the field to access its history. For data category security, Salesforce determines access based on the categorization of the online version of an article. If there is no online version, then security is applied based on the archived version, followed by the security of the draft version.
