If the edit test does not indicate that a test rule requires multiple levels of approval, the system assumes that only one approval level is required. All tests always require at least one level of business review.

Eagle strongly recommends that clients create (by copying) their own edit tests prior to converting on their business and using the application in production. You should never customize core edit tests and use them in a production environment, because when Eagle delivers its core edit tests in the next release, the customization changes (map and tolerances and so on) are overridden. You can copy core edit tests and make them non-core to customize the edits to suit your business needs. You can then customize the tolerance related tests to suit your business needs.
