ESB Networks Harmonisation Technical Design Options

18 Nov, 2010Harmonisation Working Group17 Background Retail Market Messages are currently processed through a combination of See Beyond 5.03 and a See Beyond e*Xchange Component on the MPCC hosted on each supplier’s site. Oracle (now owner of See Beyond) has indicated that Standard Support for See Beyond 5.03 expires on 31/12/2013. Also, See Beyond is not their strategic EAI toolset for the future. Assumptions for Harmonisation:- - A Harmonised Market means (1) Harmonised Market Messages operating in both NI and ROI jurisdictions and (2) a single MPCC (or EMMA as per NI) for each supplier operating in both markets. - NIE Enduring Solution will implement Harmonised Market Message Schema for Northern Ireland Retail Market in May Minimise implementation impact for Suppliers

18 Nov, 2010Harmonisation Working Group19 Harmonised Technical Design NIE SAP Pi MPCC/ EMMA Tibco Tibco / Other SAP Pi ESB SAP-ISU

18 Nov, 2010Harmonisation Working Group20 Harmonisation Delivery Options - RoI OptionsPreliminary Observations Implement Changes to Schema before NIE Enduring Solution go-live (May 2012) on See Beyond linked to current MPCC’s Additional Implementation Projects for Suppliers Replace See Beyond with SAP Process Integration (PI), Implement Changes to Schema on SAP PI Platform and Implement new MPCC before NIE Enduring Solution Go-Live Challenging Timeframe for ESB N to implement an unfamiliar product. Replace See Beyond with SAP Process Integration (PI), Implement Changes to Schema on SAP PI Platform and Implement new MPCC at the same time as NIE Enduring Solution Go-Live Additional Risk for NIE Enduring Solution Replace See Beyond with SAP Process Integration (PI), Implement Changes to Schema on SAP PI Platform and Implement new MPCC after NIE Enduring Solution Go-Live Further Analysis on Tibco B2B Application Required. All Options Still under Consideration Initial conclusion - Harmonised schema unlikely to be delivered in RoI in 2011
