About Usage Subscription Quantities
Usage subscription quantities are quantities that are stored at the usage subscription level. These quantities are calculated at irregular frequencies (such as annually or quarterly) and thus do not make sense as a measured quantity on a device and measuring component. For example, in some deregulated markets the Peak Load Contribution could be stored here and effective dated over time to represent the changing contribution of a given usage subscription to the market wide coincidence peaks.
Usage subscription quantities are defined by the following:
- Usage Subscription: The usage subscription for which the quantities were calculated
- Usage Subscription Quantity Type: The Usage Subscription Quantity Type used for the record
- Start Date / End Date: The date range for the calculated quantity
- Usage Subscription Quantities: Calculated quantities based on Quantity Identifiers configured on the Usage Subscription Quantity Type (see Understanding Usage Subscription Quantity Types for more information)
Note: There cannot be more than one Usage Subscription Quantity for
the same Usage Subscription and Usage Subscription Quantity Type,
for the same time period (defined by the Start Date and End Date parameters).
