Hello April,
Some application code shipped with the ServiceNow system requires special protection. When an application file has a Read-only protection policy, nobody can modify the related record. Only a ServiceNow employee can alter the protection policy and then modify the application file or its related record. A ServiceNow employee cannot make any changes without changing the policy designation first.
To prevent customizations from being overwritten by system upgrades, the upgrade process automatically skips changes to customer-updated records. If you modify an application file or related record that is later designated as Read-only in an upgrade, the application file maintains the default protection policy of Write. You keep the existing modifications and can continue modifying the records.
| Note: Should you revert a customized file to its baseline state, then the record inherits the new protection policy as well. This could result in a record going from a Write protection policy to a Read-only protection policy. |
