1 Introduction

1.1 Purpose and Scope of the Procedure

This BSC Procedure (BSCP) defines the process for the manual correction of errors to data in the Supplier Meter Registration Service (SMRS) that cannot be resolved using the standard update processes defined in BSCP501.

The objectives of this BSCP are to define the processes by which:

(1) Suppliers and Licensed Distribution System Operators (LDSOs) / Supplier Meter Registration Agents (SMRAs) may correct errors in SMRS, using a Retrospective Manual Amendment (RMA);

(2) Suppliers and LDSOs initiate a request for an RMA and progress that RMA where this is required;

(3) The other impacted Party’s agreement is sought, and may be given or rejected, where a Supplier’s RMA request impacts an LDSO’s SMRS data or vice versa;

(4) SMRAs notify the Data Aggregator (DA) of an implemented RMA; and

(5) SMRAs advise any subsequent Suppliers of an implemented RMA.

1.2 Main Users of Procedure and their Responsibilities

Main users of this procedure are:

Suppliers and LDSOs in their capacity as the Data Owners for those SMRS data items that can be subject to an RMA; and

Suppliers and LDSOs in their respective capacities as users and providers of the SMRS.

1.3 Use of the Procedure

RMAs are an aspect of wider error resolution processes and the relevant Data Owner (Supplier or LDSO) should always use reasonable endeavours to update SMRS in an accurate and timely manner, in accordance with the requirements of the Balancing and Settlement Code (the Code) and BSCP501. RMAs are intended for use in exceptional circumstances only. Existing methods for the resolution of data errors under the Code and BSCP501 should be employed wherever possible to prevent the need for an RMA.

The remaining sections in this document are:

Section 2 – Service Definition: this section sets out the scope of this BSCP in more detail, the principles and timescales to be followed under this BSCP, and other high-level requirements.

Section 3 – Interface and Timetable Information: this section defines in more detail the requirements of each business process.

Section 4 – Appendices: this section contains supporting information.

1.4 Balancing and Settlement Code Provision

This BSCP has been produced in accordance with the provisions of the Code. In the event of an inconsistency between the provisions of this BSCP and the Code, the provisions of the Code shall prevail.

2 Service Definition

2.1 Scope

This BSCP supports the progression of retrospective amendments to data in SMRS, as referenced in BSCP501 section 2.7.3. It sets out a mechanism to be used in the circumstances where an error has been identified for a date prior to the Current Effective From Date (EFD) in SMRS for a data item (a ‘Retrospective Error’), necessitating the rectification of that error in SMRS through an RMA.

This BSCP describes the request and execution of an RMA, but does not attempt to establish all the circumstances which might give rise to an RMA, as these circumstances are diverse. This BSCP enables the Data Owner, or a Supplier or LDSO who identifies a need for an RMA, to instigate the RMA procedures where this has been determined appropriate for error resolution.

Retrospective Errors under this BSCP are only considered within the timescales for the Final Reconciliation Settlement Run. Any RMA that is required outside of these timescales, and which has an impact on Settlement, can only be considered where:

It is supported by a Trading Disputes Committee (TDC) determination in accordance with BSCP11; or
The technical controls or validation procedures of the SMRS require the RMA to be effected for a date beyond the timescales for the Final Reconciliation Settlement Run (for example to enable contiguous data logic) in order to enable the ongoing integrity of the Metering System in question and any relevant Settlement Days.

Where a data item has been cancelled in SMRS using an RMA, this BSCP does not preclude the use of an ‘Update Registration Details’ (D0205) data flow, rather than manual input, to update the correct data, and/or to reinstate historical data that was cancelled in order to implement the RMA.

Examples of RMAs are included as Appendix 4.4.

2.2 Exclusions

This procedure may not be used to correct data items which are maintained within the Central Switching Service (CSS).

Any SMRS data items which are included in Appendix 4.1 of BSCP501, but excluded from Appendix 4.1 of this BSCP604, may not be corrected using an RMA.

2.3 Principles

This BSCP sets out the expectations and processes to be followed when an error in SMRS data has been identified that may be corrected using an RMA. It does not mandate the correction of all Retrospective Errors by an RMA, and anticipates that Parties will make an informed decision as to whether an RMA is appropriate. Having made such a decision, this BSCP sets out the framework and mechanisms for the authorisation and progression of the RMA in SMRS.

In the case of Suppliers, this BSCP is designed for the correction of individual Registrations only (i.e. relating to resolution of error(s) associated with a particular Registration) and the forms supporting this BSCP are designed accordingly. Errors across multiple Registrations should be handled as a set of individual errors, unless otherwise agreed bi-laterally between the parties concerned. Suppliers are only responsible for their respective SMRS data items during their Registration and can only effect changes for this period.
The SMRS data items for which an LDSO is responsible may span multiple Supplier Registrations. Therefore, the LDSO may be required to make RMAs which are effective for more than one Registration period. In this case, the LDSO will ensure that it liaises with, and obtains agreement from, all affected Suppliers prior to implementing the change (in its capacity as SMRA).
Where a Supplier or LDSO requires an RMA, and that change will also have an effect on the other’s data, then both Data Owners should agree to the change, since it is an objective that data is corrected consistently. Suppliers and LDSOs shall use reasonable endeavours to resolve any disagreement, failing which the provisions of Section H7 of the Code shall apply.
Where an RMA has been implemented, the SMRA will inform all relevant DAs of the change using an ‘Instruction(s) to Non Half Hourly or Half Hourly Data Aggregator’ (D0209) data flow, which may be in the form of a Selective Refresh. Should an RMA cancel a DA’s appointment, then the use of a single Metering System refresh to the DA(s) to advise them of this is still an appropriate means of communication, unless otherwise determined by the SMRA.

2.4 Timescales

The Data Owner, or any Supplier or LDSO who identifies a need for an RMA, is responsible for instigating a request for the RMA.

Before initiating an RMA, the Supplier or LDSO will use the Settlement Calendar to establish the latest date for which changes can be made and still be included in the Final Reconciliation Settlement Run.

Where the EFD for a Retrospective Error is near the Final Reconciliation Settlement Run date, the Supplier and LDSO shall discuss the schedule required to implement the RMA. Where the RMA is unlikely to complete, taking into account the timescales in section 3 and the Settlement Calendar, the RMA shall only proceed if subject to an authorised Trading Dispute or the conditions described in 2.1(b) apply.

2.5 Changes to Disconnection Date

Where a Supplier or an LDSO becomes aware that a Disconnection Date in SMRS is in error, the LDSO shall confirm the actual Disconnection Date to its SMRA for the relevant Metering System. The LDSO shall issue a BSCP604/02 form (see Appendix 4.3), or communicate with the Supplier using the Secure Data Exchange Portal (SDEP) or other bilaterally agreed method, noting the correct Disconnection Date, from which date further Registrations are to be prevented.

Amending the Disconnection Date will not impact the Effective To Date (ETD) for data in the Registration. The Supplier will continue to be registered and all related SMRS data items will continue to be effective until the CSS has successfully processed a Registration Deactivation Request. A Disconnection Date cannot be amended, or the status of the Metering System changed from disconnected, once the Registration Status has been set to Inactive.

In all instances where a change to Disconnection Date is made, the SMRA will ensure that affected Supplier(s) are notified of the LDSO changes to Metering System details.

2.6 Communications

The process for requesting, quoting for and authorising an RMA is defined in section 3.

Information exchanges should be via the SDEP or by other means agreed bilaterally by the Supplier and LDSO.

Suppliers and LDSOs/SMRAs should use the forms in Appendices 4.2 and 4.3, or an alternative form of communication by bilateral agreement. In the event that an alternative method of communication has been agreed between the Supplier and LDSO, the appropriate information, authorisations and audit trail shall be maintained in keeping with the forms in Appendices 4.2 and 4.3.

2.7 Data Integrity

When completing RMAs, the requester should ensure that combinations of data items are consistent with Market Domain Data (MDD) and the SMRS validation rules set out in BSCP501 Appendix 4.3.

Where the RMA is in respect of a cancellation of a Supplier Agent appointment, the Supplier shall ensure that both the incorrect and correct Supplier Agents align data with the RMA. Particular care should be taken when an RMA involves the cancellation of an incorrect Supplier Agent and the appointment of another for a period, due to the extra complexity of informational exchange.

Suppliers should ensure that, whenever an RMA is made, all relevant Supplier and Supplier Agent systems are updated as necessary with the correct information so that consistency is maintained.

Suppliers should ensure that they inform their Supplier Agents of intended RMAs, as required.

Once records are updated under an RMA, the SMRA will:

Send a D0209 instruction to all affected DAs, which may be in the form of a Selective Refresh;
Advise the LDSO of the changes (internal communication); and
Advise future Suppliers of the changes.

Notwithstanding the SMRS validation rules, the SMRA shall not be obliged to check the validity or accuracy of any data items provided by a Data Owner in its instruction for an RMA.

2.8 Contacts

Each LDSO/SMRA shall appoint a dedicated contact who will be responsible for RMAs under this BSCP.

Each Supplier shall appoint a dedicated contact who will be responsible for RMAs under this BSCP and who will be the point of contact for SMRAs in fulfilling the requirement to notify future Suppliers, where applicable.

The contact details above should also specify the MPID(s) which each contact represents. This list will be published by BSCCo. Each LDSO/SMRA and Supplier is responsible for providing BSCCo with up-to-date information.

2.9 Audit Requirements

All documents associated with a particular RMA should be retained in keeping with the general requirements under Party Service Line (PSL) 100.

SMRAs should maintain a log of all RMAs that are implemented, recording:

The unique log number for the RMA;
The Supplier or LDSO Id (as appropriate to the data item that has been amended) and name and designation of the person who authorised the RMA;
The reference number specific to the RMA; and
The date the RMA was implemented.

The Metering System history should include the user id and relevant access level of the operator who implemented the particular RMA. A data integrity check should be conducted before and after implementing the RMA and should be auditable. A file note should also be made against the relevant Metering System confirming the reference number used for the RMA as appropriate, so that this can be cross-checked.
