Calculation Period Proration

There can be multiple versions of a given rate over time. Each version has an effective date. When the system detects that a rate schedule has multiple versions of a rate in effect during a bill period, it may or may not prorate the charges. You control exactly how the system handles this situation using the rate schedule's proration parameters.

If multiple rate versions are effective during the consumption period and the rate schedule is configured to prorate the rate versions, a given bill segment will contain a set of bill calculation lines for each rate version. You should consider quite carefully how to handle this situation on your printed bills as rate version proration can confuse a customer.
