IPT scenario definition Script Name: IPT005 Unsuccessful Change to Meter Configuration Code Test objectives: The Supplier receives and correctly interprets the requested Meter Works Status from the new market message, MM131. Participant roles under test: Supplier, ESB Networks Participant roles requiring simulation: None.   Initial Conditions: The Metering Point is registered to the Supplier with all Registration Data items set; The Metering Point is currently energised; The Supplier has a recorded history for the Metering Point; and The Supplier has retained evidence of all of the above. The Scenario: The Supplier requests a change of Meter configuration code by submitting a meter works (MM030) request, with no CoLE to ESB Networks Central Market Systems; ESB Networks validates the meter configuration is from the standard set and that both the meter work request and appointment date are valid and that all permits and requisite requirements to perform the meter works are in place. ESB Networks is unable to perform the change as they are unable to access the customer’s site; ESB Networks reschedules the visit, updates their records, and informs the Supplier via relevant market message (MM131). Test Ends Final Conditions: The requested Meter Configuration Code change is not performed; The Supplier receives the new MM131 (Work Type W103 and Outcome Reason (R001)) informing them of the status of their requested meter works; and The Supplier processes the new MM131 according to their business processes.

IPT028 Supplier provides customer reading with the meter serial number 1. BGE submits an invalid Customer Reading (MM210) including the Serial Number which is now required for validation; 2. BGE receives the Validated Reading (MM300) 1. XML of MM210 (sent); 2. XML of Vlaidated Read (MM300) (received); IPT042 Readings Processing - Non QH The Supplier receives and process their standard NQH reads using their normal business processes as per business as usual (BAU).
