  42. Market Change Request MCR 158 – Changes to ARIS Data Definitions • MCR circulated on Thursday 22nd November • Approval requested 42

  43. Discussion Request DR 0117 - Proposal to add Acceptance, Completion and Cancellation messages to Meter Works design • Feedback from one participant raised issues about the process for cancellation of Meter Works/De-energisations/Re-energisations • Further internal ESB Networks discussions ongoing • Valid ‘cancellation’ codes will be added to 131 message when the DR is re-circulated (Action Item 70) 43

  44. Market Change Request MCR 0154 – Versioning of the 341 Propose to rename the MCR from ‘Versioning of the 341’ to ‘Versioning of the Meter Data on the 341 Market Message’ Question raised – How will the MCR handle version numbers for import and export data • Proposed Solutions for MCR 154 • Solution 1 Provide a separate Version Number at the MPRN level for Import and Export data and a read replacement flag at the Channel Level Details which would indicate the channel being updated. • Solution 2 Provide a Version Number at the channel level. This would mean that the Import QH kW, Import QH kVAr, Export QH kW and the QH Export kVAr would each have a version number. The Read Replacement Flag would no longer be required as the version would indicate the reading being replaced. Longer term raise a new DR to build a new message 342 for Export data only and use 341 for import data only. 44
