Rate schedules (static)
From Dot2DotCommunications
Rate schedules are assigned to each Face as appropriate. Each Rate Schedule can be used by one or more Faces if these faces always have the same published rate. The Rate Schedule is a grouping of Rate Card(s) that apply to the Face.
A Rate Schedule can contain multiple Rate Cards. Each Rate Card comes into effect on a specific date. When calculating the Rate Card Value of a Contract (as opposed to the value being charged the client), Ad Manager will use the appropriate rate for each day.
