Objective
Full project delivery of UK Link Future Release 2 Scope
Post Implementation Support
8 changes have completed first usage while 8 changes are in the process of completing first usage due to extra confidence runs due to defect fixes
The first usage will be completed by 7th September for all the changes except for the historic data load activity involved for XRN4299
The PIS end date is extended and planned to complete on 2nd November due to the completion of change variation on XRN4299, there are no additional costs involved
XRN4299 – ‘No Reads’ report to be delivered on 22nd August
XRN4449 – There was an issue reported on the one off Shipper report which has been communicated to the individual Shippers and we are working through the fix to be delivered by end of next week 24th August 2018
Close down activities have commenced for Release 2 and we are targeting to deliver the change completion report in October 2018
Risks & Issues
There is a risk that PIS exit is not achieved by the re-planned milestone date
Project delivery costs are tracking to approved budgets
Weekly monitoring of SME resources supporting multiple demands (e.g. BAU defects, Future Releases, etc) and all requirements are able to be met

Objective
Full project delivery of UK Link Future Release 3 Scope
Extraordinary Change Management Committee on 23rd of July approved the split delivery of Release 3 scope into 13 CRs on 2nd of November and XRN 4454 to be delivered on 1st February 2019
The progress against each track is as below:-
Track 1 (13 Changes) – Build and System Testing complete, Acceptance testing in progress and on track. MT preparation ongoing. Slight delay in plan due to Environment and data build activities. No MT delivery impact envisaged at this stage
Track 2 (XRN 4454) – The revised Build Plan is tracking Green. System Testing is now underway
The Market Trials approach presented to DSG members on 6th August and was well received with no major changes highlighted. Registration period for MT was due to close on 14th August however this was extended to 1pm on 17th August. Weekly pre-meetings have been arranged from 17th August onwards to talk through specific MT topics in more detail. Data provision for participants to be shared from 23rd August onwards for those parties that have registered, preparation of this data is ongoing.
Business Change activities are in progress and a schedule for external training was presented to DSG on 6th August. The first training session has been arranged for 21st August and will be available via Webex. A number of participants have already registered for the both training sessions in August. Preparation for the customer day on 5th September is in progress
XRN 4658 (BER approved by ChMC on 23rd July) now included in R3 plan with build complete and testing in progress. Due to the late inclusion of change, a close monitoring of progress to enter MT is underway.
Risk to MT preparation timescales due to Environment technical and data issues – this is being managed
Go Live date dependent on close management of parallelism in plan, which has increased due to Build completion delays (being managed and is currently tracking Green) and other elements i.e. Agreement of MT approach/ Implementation plan agreement.
XRN 4658 may not meet all MT requirements on Day 1 (risk is being managed)
Full Delivery costs approved at ChMC in April Revision expected to accommodate XRN 4454 delivery date (ongoing discussions)
Greater resource needed for XRN4454 (both technical & SME) for fulfilling the need for extended build. Daily tracking of Build plan in place to ensure progressing to revised timelines and additional resource support to deliver XRN 4454
SME resource requirements for Build, ST and AT phases is being managed weekly with internal Xoserve teams.

PLEASE NOTE:
Shippers should ensure outbound files are moved to the correct folders as stated below
Market Trial files to E:\XXXXX\General\export
If the above is not done correctly then files will be moved to an error folder and this will delay the processing of files.
Also, it may corrupt data in the production UKLink system.
Use only File name starting with TNxxxxxx.ABC not PNxxxxxx.ABC
Please do not send duplicate files –stakeholders should not send files that have already been sent to Xoserve previously
and have been processed successfully

26. 8. New Changes Proposals

27. New Change Proposals
The objective of this slide is to inform DSG attendees of one new Change Proposal and it’s prioritisation score
8.a. XRN4725 – New read reason type for LIS estimate readings

28. 9. Change Proposal Initial Review Representations

29. 9.a. 3667a – Provision of Prospective Formula AQ/SOQ to Proposing Users

30. Story so far…
XRN3667a was raised to look into solutions to allow the proposed Formula Year (FY) AQ/SOQ values to be visible to proposing users
4 solutions discussed at DMG ( ) with API being the favoured solution
DSG agreed to extend scope to include AQ/SOQ history ( ) work looking into permissions for this is ongoing
DSG agreed to extended scope to include Suppliers ( )
Agreement to split XRN3667a into 2 phases (DSG )
Phase 1: Delivery of API to show current/proposed Formula Year AQ/SOQ
Phase 2: Enhancement or new API to include AQ/SOQ history data
CP (XRN Ref TBC) raised to look at issuing notification of Financial Year AQ/SOQ to current system users following discussions with DSG members to mitigate potential misuse of the API service (DSG )
API solution for FY AQ/SOQ to be fed into September’s JMDG via a new use case

31. Ongoing Assumptions
API solution to be used for NDM (Class 3 & 4) MPRNs only, if search is carried out for DM (Class 1 & 2) MPRNs an Error Message or BLANK details will be shown (depending on build options) as Class 1 & 2 sites do not have Formula Year AQ/SOQ values
Proposed AQ/SOQ values will only be present once calculated, if search is carried out between April & November these will either be BLANK or match Current AQ/SOQ values (depending on build options)
Solution based on assumption that users have the required access/permissions to the API solution and the agreed data items (API Data Matrix is in the works to support this and future API requests for data)
Solution is to be used by perspective users to identify proposed FY AQ/SOQ values to facilitate a more reliable switch

32. Discussion Points
DSG held on requested additional details on the following…
What would happen if the API system is down outside of the 08:30 to 17:30 period?
If the API service is down outside of the helpdesk hours stated above then the service will remain unavailable until such a time as the helpdesk re-opens
Overview of the funding arrangements for this API service.
Funding for the build, test and implementation of this API service is being done so via the Business Improvements budget
However access to API platform and usage of the FY API is a chargeable (non-profit) service (indicative costs below)

33. 9.b. 4645 – RGMA Flows with Incrementing Readings on Isolated SMPs

34. Preliminary Data Findings
DSG asked for views on materiality - to help determine solution options
Preliminary Data Findings
On average there are 8 valid readings during the isolated period
Average consumption of Supply Meter Points within sample c44,000 kWh (volume c4,000 m3) between isolation and reconnection readings
c 10% of Supply Meter Points included have consumption less than 100 kWh
This suggests that this is not commissioning gas – views?

35. Solution Options
DSG asked us to consider an option to accept the transaction as it was expected that this was small volumes of gas associated with commissioning
Some instances do appear to be within this category,
The majority appear to be isolation reversal notification not having been received following physical activity, some of the periods are very extensive
This solution option would have been complex to implement due to impacts to reconciliation principles, assume that:
Reconciliation would need to be generated using original Isolation Reading – potentially for the reversal date included within the RGMA transaction? – otherwise would lead to unreconciled gas
Original solution proposal was to reject the RGMA transaction, indicating that an incrementing reading was included in the transaction
Suggest that notification provided to MAMs to reduce commissioning exceptions

36. 9.c. 4713 – Actual read following estimated transfer read calculating AQ of 1 (linked to XRN4690)

37. Impacted Applications
Change ID
Change Description
XRN 4713
The change is to get around the issue of system having to calculate the AQ on the back of negative consumption. If the AQ is already calculated, corrective action needs to be taken at the earliest opportunity.
High Level Solution Overview
Re-estimate the estimated read once the actual read has come
In this option, the system will re-estimate the read once the actual read comes in. Since the re-estimated read will be less than the actual read, negative consumption can be avoided.
Solution Specific Assumption:
The system impact for this option is high as the solution needs to touch all the possible read sources. Also, the re-estimated read may have to be communicated to all the stake holders. Additional considerations have to be met if the estimated read is already reconciled and already billed.

39. 10. Solution Options (IA)

40. 10a. 4676 – Reconciliation Issues with Reads Recorded between D-1 to D-5

41. Story so far…
An issue was identified where a cyclic read is received by an outgoing shipper for the same day as an FINT read (outgoing shipper transfer read D-1)
Issue is causing duplicated energy/charges for a one day reconciliation between cyclic and FINT reads on Class 4 sites
Current system logic cannot have 2 active reads for the same day
Over 30k instances have been identified to date
Although issue has only been experienced for D-1 solution options are proposed to cover D-1 to D-5 (where appropriate) to prevent any potential issues occurring
Defect 914 will identify impacted reconciliation periods and correct those already released. Any newly identified reconciliation periods are being held from the invoice
5 solution options were presented at DSG on with a 6th option being put forward
DSG members recommended that options 1, 2 & 6 are disregarded and 3, 4 & 5 are taken forward for Impact Assessment

42. Potential solution options (02.07.2018)
Reject readings received between (D-1 to D-5) of CO confirmation using current Rejection Code
Proposed: “SPO request denied as supply point ownership is subject to transfer”
Use Outgoing Shippers cyclic read as the Shipper Transfer Read (FINT/OPNT)
This would require a new MOD
Set the transfer reading for Class 4 transfer reads as the Transfer Date rather than the actual read date (D-5 to D+5)
Will still be an issue for D-1 reads
Make the read supplied by Outgoing Shipper ‘invalid’ and undo any reconciliations
Will need to assess from an UNC perspective
Allow 2 reads for a single day on UK Link but have differing read types
Allow for the cyclic read to be accepted and then rejected at a later date

43. Early indication of Impact Assessment
3. Set the transfer reading for Class 4 transfer reads as the Transfer Date rather than the actual read date (D-5 to D+5)
This is how the current process works so no additional assessment has can be carried out
4. Make the read supplied by Outgoing Shipper ‘invalid’ and undo any reconciliations
Systems Impacted: SAP ISU
Process Impacted: Read Process, Reconciliation Process, SPA
Change Complexity: High
Allow 2 reads for a single day on UK Link but have differing read types
Initial assessment indicates that SAP functionality doesn’t support the processing of two active reads on the same register for the same day

44. Proposal (5b)
However when the initial Impact Assessment was being discussed an additional option was produced, 5b
SAP is unable to have 2 active reads on the same register for the same date, but acceptance of multiple readings is possible with a view to be used in different processes
It is proposed that when the Outgoing Shipper submits a cyclic read between D-1 & D-5 of the Shipper Transfer Effective Date, this read is accepted into UKL but set as inactive
If the Incoming Shipper does not load a cyclic reading within the Transfer Read Window (D-5 to D+5) then UKL will estimate a reading on the Shipper Transfer Effective Date (BAU) but use the Outgoing Shippers inactive cyclic read in the estimation calculation (new process)
This would make the Shipper Transfer Estimate more accurate to what is physically being off taken at site as the Outgoing Shipper read would be used

45. Proposal (5b) continued…
If the Incoming Shipper does load an opening reading within the Transfer Read Window (D-5 to D+5) then UKL will (in accordance with UNC) use this read as the Shipper Transfer Reading effective on the Shipper Transfer Effective Date (BAU)
Accepting the Outgoing Shipper reading (within D-1 & D-5) but setting it as inactive will ensure that we do not restrict the possibility of an Incoming Shipper submitting an opening reading
The Reconciliation process is unaffected and remains BAU (Rec will still go from Cyclic Read to Shipper Transfer Effective Date in all instances)

48. 10.b. 4687 – PSR Updates for Large Domestic Sites

49. XRN4687 - PSR updates for large domestic sites
To date, 6 solution options for XRN4687 have been discussed
Initially, DSG agreed that option 3 (Change the validation threshold from 73,200kWh to 732,000kWh) and option 4 (Remove the validation) should be impact assessed as potential immediate solutions. It was confirmed that both of these options relate to validation changes on the Customer Amendment file (CNC) only
At the last DSG, members agreed to consider another solution, (option 6) for impact assessment which would allow PSR information to be sent on a confirmation of a LSP. This option could be a potential longer-term solution as it would be an amendment to the CNF hierarchy to allow the S84 – Priority Services information to be sent with a confirmation
Following the meeting, the request to reconsider option 2 (Move the validation from AQ to Market Sector Code) has been raised. It has been highlighted that this option could also be a longer-term solution and assist to improve data quality
The intention is to discuss this option at DSG on 20th August and solicit views from members regarding considering option 2

56. 12.b. Contact Management Service response file content (.QCL file)
Customers familiar with the Contact Management Service (CMS) will be aware that all Contacts raised are assigned a unique reference known as a Contact Reference Number
When Contacts are resolved an , known as the QCL file, is issued to the raising User
This response contains each of the Contacts resolved (by Contact Reference Number), and describes whether the Contact was resolved as valid or invalid by UK Link systems
Customers have fed back that it would be beneficial to include additional data items within the QCL file, namely;
MPRN,
Resolution text, and if relevant;
Associated QMP file details (i.e. file name)
These items have been identified as being able to better assist Customers to process any Contacts that have failed to successfully update UK Link systems
As the QCL file is an interface all Customer Classes have with CMS we welcome views from DSG members on the following;
a) Whether changes to the QCL file would be supported?
b) Whether you support the suggested data item additions?
DSG members’ view’s will be used to help take this initiative forward if it is deemed necessary

57. 12.c. Xoserve IX Refresh Customer – Overview Change Pack – August 2018
To provide DSG with an update on progress

58. Have you got all of the site information required?
IX Site Survey
We issued site surveys to all of our customers in May and have been busy working with you over these past few weeks to obtain your site information.
As of the 27th July, we have received 140 completed responses (82%), and 27 (19%) of you are in contact with us and we hope to have your site information soon. We have yet to achieve contact with just 3 sites (2%) but we are still actively pursuing contact. If you would like to check whether your survey has been submitted, please contact us at or call
We will not be actively chasing site responses after 31st July. Those we receive after this point will be planned in at the end of roll-out plan.
Have you got all of the site information required?

59. Hardware Installations – Circuits
We have now issued communications to those customers included in the first batch of circuit installations. These are sites for which we have received a completed site survey and have little or no access requirements. The communication provides a high-level view of activities for your installation - based on your IX Option (see Appendix A).
The circuit installation appointments for these sites are now being issued from Gamma, and work has commenced from 23rd July. Statistics for these appointments (successful, failed, follow up appointments needed, etc.) will be available as we progress through the plan.
What’s the progress with the installations?
What if I haven't yet received a communication or appointment?
We are still in the process of planning site visits, continuing to prioritise those sites with few access requirements. It may also be that we are still awaiting your Site Survey.
Those customers who have received a site communication can expect an appointment from Gamma (GNS Project Provisioning) to follow shortly. Please accept the appointment date if you are able to grant access to the BT OpenReach engineer on that day, otherwise, you will need to reject the appointment with a reason and confirm suitable dates for your circuit installation.

60. Next Steps July Pursue the last few Site Surveys from organisations
Aug
First batch of New Circuit Installation & Connectivity Testing
Aug
Further planning and checking Site Access Requirements
Sep
Second batch of New Circuit Installation & Connectivity Testing

61. Appendix A: IX Service Line Options
Xoserve are replacing your IX kit on a ‘like for like’ basis, therefore your replacement IX service option and contract will match the IX option you currently have, which will be one of the following:
Option 1 - Primary ADSL and Back-Up ADSL connection
Option 2 - Primary EFM and Back-Up ADSL connection
Option 3 - EFM Primary and EFM Back-Up connection
Option 4 - Primary Fibre/ Ethernet and Back-Up ADSL connection
The following slide displays the on-site installation process; the number of site visits that are required is dependant upon your IX service line option complexity.

62. Appendix B: Your Customer Journey
The number of days required to complete the activity will be dependant upon your IX Service option
Day 1
IX Survey Response
A number of remote off-site activities also take place to assess your site’s requirements and to set-up and test connections and configure hardware

Decommissioning
Engineer(s) will visit your site to install new circuits; the number of site visits and the access method will vary according to your IX service option and site complexity
The Router Installation will take place in one site visit
Key:
Site Visits
The new server will be installed with the existing Vodafone server still in situ to enable a fall-back position. Where rack space concerns exist, we will address this on a case by case basis
Comms
Notes
Your old service will be removed and wiped by Vodafone and disposed of in accordance with regulations

63. 12.d. 4650 – M-Number DVD Automation

64. Story so far…
The purpose of XRN4650 is to provide an alternative delivery mechanism to the M Number DVD via download service
The process of transitioning to the alternative delivery mechanism is to be run in parallel of the current delivery mechanisms, however the USB/DVD is to be decommissioned later at date (initial indication after a 12 month period).
XRN4650 was discussed at ChMC on 8th August for information only. Change Managers requested for the change to be referred to DSG for technical consideration.

65. DSG Considerations
DSG members are asked to consider the feasibility of a download service to understand potential limitations from an individual organisation perspective.
The download service is a replacement deliver mechanism, no changes to the M Number data items, file format or file extension are in scope of this change.
M Number DVD is the driver for the download service, however the intention is to move additional services provided via DVD/USB to download at a later date so please include these in your considerations
To confirm, Contract Managers will be notified of the phasing out timelines for the M Number DVD/USB service once this has been fully scoped and your considerations will feed into this.

66. 12.e. 4665 – Creation of New EUC Categories

67. Overview
XRN4665 was discussed at ChMC on the 11th July 2018 with the following approvals:
Solution: Option 2 - New EUC with same UIG Share Factors
Delivery: Option B - New Gas Year October 2019
The delivery will be split into 2 stages
