Do we need to use rates for when creating a labor budget?

Summary:

Our customer will be uploading large budgets into Projects. The do not want to use actual or planning rates for budget purposes. I have not attached planning or actual rates to the plan type or organization costing rules. When I enter or upload budgets for my labor resources, I get these errors below. We don't configure costing rules because all labor comes in pre-costed (labor is loaded as currency vs hours). We don't need Oracle to do costing for labor. Does anyone know how I fix this? Do I create zero-dollar rate schedules or is there
