To deactivate this validation please see 7.2.2.9 Feature Setting to disable Ad Price Validation.
4. The billing category differentiates between types of accounting. You can choose between fixed prices and variable billing categories, such as Cost per Click (CPC). Read more about your 3.1.4.4 Billing Categories here.
5. Prices can also be deactivated if they are not to be used for a certain period. As a result, you keep previous prices in your database. Hence, you are able to track the development of your prices. Please also refer to 3.1.9 Active and inactive inventory items.
6. Depending on the billing category add a list price.

You can create multiple ad prices for your ad spec. For example, you can create a CPM price both for US Dollar and Euro. Or create multiple ad prices for different rate criteria.
