MRA Data Transfer Catalogue (DTC) Change Proposal Form YOUR REFERENCE ORIGINATOR (MRA Change Administrator) DTC CP NUMBER (assigned by Gemserv Change Co-ordination) SPONSOR APPROVAL (MRA Contract Manager) 3220 Originator name: Emma Howlett (on behalf of the Issues Resolution Expert Group) Name: Jon Russell Company: Gemserv Company: British Gas Trading Telephone number: 0207 090 1024 Telephone number: Fax number: 0207 090 1001 Signature: Date: 08/10/2003 Date: CHANGE PROPOSAL TITLE Amend the Valid Set for the Domain String and add notes DESCRIPTION OF CHANGE Changes to Domain String to: 1) Include special characters within the valid set, and 2) Add note to highlight the Valid Set for Domains String and Text is identical Attachments Supplied? Formatted BUSINESS JUSTIFICATION FOR CHANGE There is currently 55 data items within the DTC that have the Domain String (refer to list below), the current valid set for this Domain currently reads Any alpha and/or numeric characters where alpha characters are in the standard English language set, however 12 of these Data Items (highlighted in bold) highlight special characters within the valid set, therefore to remove this discrepancy there is a requirement to amend the Valid Set for the Domain String to include Special Characters. Parties have also queried the difference between string and text, therefore to add clarification regarding this issue a note has been added to the String domain. IMPACT ASSESSMENT (Guidelines for suggesting implementation dates: 6 months min for changes impacting systems and software; 4 months min for changes impacting operational procedures; or 2 months min for changes to documentation only). Big Bang (This is the default implementation method. Participants to implement change on the Implementation Date) Optional (Participants can implement at any time from the Implementation Date, as agreed between parties) Proposed Implementation Date (if appealed this date may need to be revisited to accommodate the lead times suggested above.) (NB MDNS Upgrades occur in May, August, November, February) Implementation Date May 2004 DTC Release
Parallel Test (Participants to test from Parallel Test Start Date as agreed between parties. Participants to implement change on Implementation Date. Please note that if Parallel Testing using a new Flow Version Number is Proposed, this CP needs to be accompanied by another CP to remove the old version number of the Flow.) Parallel Test Start Date Parallel Test End Date (Implementation Date default is 3 months after the Parallel Test Start Date) Value of Test Flag (only to be completed if a specific test flag is required) Identify any organisations impacted or associated changes required.
