Usage subscription types are used to define the types of usage that can be stored for a service point, such as consumption, demand, or generation. Usage subscription types have the following attributes:
Valid Usage Recipients: A list of usage recipients for which this usage subscription type is applicable. A usage recipient is an entity that receives usage from a service point, such as a customer, a utility, or a third party.
Valid Service Point Types: A list of service point types for which this usage subscription type is applicable. A service point type is a classification of service points based on their characteristics, such as metered, unmetered, or virtual.
Valid Usage Calculation Groups: A list of usage calculation groups for which this usage subscription type is applicable. A usage calculation group is a collection of usage calculation types that define how usage is calculated, such as interval, register, or profile.
Valid Dynamic Option Types: A list of dynamic option types for which this usage subscription type is applicable. A dynamic option type is a type of option that can be used to modify the usage calculation process, such as estimation, editing, or aggregation.
Therefore, usage subscription types define the valid service point types and the recipient of the usage, but not the main billing contact or the time zone. References:
