The behavior for the fields on the Duplicate Tariff Elements: Start page vary based on the source of the request:
For Create Tariff Version and Duplicate Tariff, the Source Tariff ID defaults based on context and is not editable. Default settings for the five “Copy” fields on this page (Copy Services, Copy Lanes, Copy Rates and Copy Surcharges/Discounts, Copy Distance/Transit Time Overrides) are established at the time the page is initially loaded.
For Duplicate Tariff Elements, you must specify the Source Tariff ID. Once this ID has been supplied on the Start page and the Refresh icon has been clicked (or the Source Tariff ID has been selected via Secondary Search for Tariffs), default values are established for the five “Copy” fields.
Each of five “Copy” fields is displayed as a selected check box when applicable data exists for the source tariff. If there is no relevant data, the “Copy” field is read-only and default to False. At least one check box must be selected.
