Susan Morrissey, RMDS 32

33. Discussion Request
DR Amending Generator Unit ID and Generation Unit ID
Documentation update - no change to the schema
Correcting past inconsistencies in the use of two similarly-named data items: Generator Unit ID and Generation Unit ID
Generation Unit ID is a field that appears on various market messages, and is also a legacy data value
Generator Unit ID is an SEM data value that is one of three different values that may be stored in the Generation Unit ID field in different circumstances
DR 151 proposes documentation amendments to previously-issued MCRs:
Minor supporting text changes to MCRs: 060, 066, 077, 094, 095, 096, 097, 132, 134
Re-issue of MCRs containing changes to message definitions: 112, 120, 143 33

Re-issued to the market
Approval requested 37

38. Market Change Request MCR 0154 – Versioning of the 341
Question raised – How will the MCR handle version numbers for import and export data
Proposed Solutions
Preferred Solution - Provide a separate Version Number for both Import and Export Channels
This will require a new Channel Type Flag at the MPRN Level
Build a new message 342 for Export data only and use 341 for import data only
Scenario
Channel Type Flag (Export/ Import)
Import Ver No.
Export Ver No.
Start Point 05 02
New Exp Data E 03
New Imp Data I 06 38

39. Action Item 41 – QH to QH meter replacement
Proposed Process
1.   NT replaces QH meter with another QH or removes a QH meter 2.   PDS update MV90 (normally be same day on foot of NT phone call) 3.   PDS send an to MRSO cc with the details shown (template below) 4.   Database contact local area to ask them to Finish the call in Areas 5.   MRSO time slice the profile allocation for the MPRN 6.   MD database update SAP.  The 331 meter works market message issues. 7.   MD Database advise MRSO to re-allocate profile 8.   MRSO re-allocate the profile 9.   Paper CX arrives in MD database 10. MD database verify that it matches the details already entered (see notes 2 and 3 below) MD database notify PDS if any discrepancy 39

40. Action Item 41 – QH to QH meter replacement (contd.)
Notes:
A new QH meter may be installed some time before it registers consumption:
No profile will be allocated to the meter
SAP will not look for  consumption from that meter.
A profile is allocated to the meter on the first day that it registers consumption.
LV to MV changeover:
total site consumption shared between a new meter and an old meter during changeover. 
The 'date of exchange' will be the first date that the new meter registers consumption 
The total consumption will be  allocated to the new meter from that date.  (In SAP the profile will be reallocated from that date also.)
The paper CX will show an earlier date of installation for the new meter.
Simultaneous changes of CT and/or VT ratios will also be advised on the template. 40
