Smart / Advanced Readings

Description
This interface is to allow Cumulative Reads and/or, Smart/Advanced Register Redings, to be exchanged in a number of business scenarios. Following MHHS implementation, in most cases consumption values will be available directly from the meter. However, there may be occasions when consumption may not be available, therefore a Cumulative Reading will need to be captured/shared as a 'fall back' measure
Notes
For the avoidance of doubt IF-041 pertains to the exchange of meter readings, therefore is not of relevance to a UMSDS. MS: [ReadingRemv], [ReadingInstl], [ReadingEnergisation] ~ used by the Metering Service to exchange Cumulative Readings for associated metering events. DS: [ReadingRemv], [ReadingInstl], [ReadingEnergisation] ~ used by the Data Service to Estimate Cumulative Reads in rare situations when a reading might(s) not be available. DS/MS: [Reading Onsite] ~ used by Data Service if on-site reading(s) have been captured for a Smart/Advanced Meter. SDS: [ReadingCOS],[DSEstimate] ~ Actual or Estimated Cumulative Reading associated with Change of Supplier / Change of Data Service. SUP: [ReadingCOR], [ReadingCOS], [SupplierAgreedCOS], [ReadingOverride] ~ Supplier Originated readings . At the working group's request, the design does not include any response or acknowledgement [by the SDS] of readings received. However, there is a clear principle that the SDS will always use actual data available from the meter as its primary preference - the only exception to this being where a partner Supplier provides a [SupplierAgreedCOS] or a [ReadingOverride] Reading. It is assumed that Suppliers will be performing reconciliation between the IF-021 messages issued by their partner SDS into Settlements, and copied to them via the DIP; and their own record(s) of consumption so as to identify any discrepancies. When exchanging readings between parties the design assumes that in the most part this will be the Cumulative Register Reading (Block B064). However, at participants request this message also allows for the exchange of Configurable Register Readings (B065) either alongside a Cumulative Reading or in isolation. For the avoidance of doubt the message must contain at least one B064 record and /or one (or more) B065 records [depending on the number of configurable registers], in order to be considered valid. An IF-041 sent by the Data Service will route to both the Incoming and Outgoing Supplier if the Cumulative Register Read Date/Time (DI-089) is set as midnight on the COS date. ie the midnight cumulative read has been provided. *Routed to both Outgoing and Incoming Supplier where required **During a Change of Segment the IF-041 needs to be sent prior to the segment change for the Removal Read and after the segment change for the Install Read.
