Maintenance Resource Rates vs. Resource Rates Set up in Costing

Summary:

Maintenance Resource Rates vs. Resource Rates Set up in Costing - What is the difference and how are these used?

Content (required):

I have a provision to add rates to resources in the Resource Definition page. However, when costed, these rates are not considered and error is thrown that costs are not part of scenario. Doesn't the scenario consider the rates defined in the resource window? If not, where else is this information at Resource level used?
