5 Executive Summary This White Paper describes current SAP solution: Process and Data-Exchange for Utilities, its implementation approach based on generic requirements for Utilities Energy industry and evolution of the solution in its current form based on past projects. Background In many countries, the utilities industry is experiencing massive transformation due to deregulation. Deregulation has resulted in incumbent utility companies becoming separate independent entities covering only parts of the total value chain from power generation through distribution to end-user sales and service. This transformation has significant impact both in terms of managing business processes for each independent entity and also exchange of data across companies General Issues for market communication Process Logic distributed across several entities Basic Process infrastructure needed to build, execute and monitor end-to-end process Inbound/Outbound message communication rules need to be transparent and flexible Robust change mechanism for adjustments needed in case of regulatory changes Need for standardized Error handling and manual data correction SAP s Answer SAP Process and Data-Exchange for Utilities solution provides mechanism of market communication for Intercompany processes in deregulated utilities markets which includes: Market format implementation Market Process modelling and choreography that can result in creation/change of master/transaction data and exchange of information with other market participants.

8 Architecture: Process and Data-Exchange Framework The process and data-exchange framework for utilities is a generic software solution to manage intercompany data-exchange processes as required by energy deregulation for the energy supply of metered metering points and unmetered sites and the corresponding market communication. For communication between solution in the ISU system and the EAI system, IDocs or webservices can be used. The following picture provides an overview of the architectural elements of the Process and Data-Exchange infrastructure Figure 3: Architectural view of the Process and Data-Exchange Framework for Utilities D Walldorf Page 8 of 21

9 The light yellow and green coloured boxes are elements of the Process and Data Exchange Framework The light yellow boxes in particular describe those elements of the Process and Data- Exchange Framework which most likely could be affected by regulatory or customer imposed changes to the message or process flow. The dark gray box on the left represents the EAI (Enterprise Application Interface) system, for example SAP PI. This system is, among others, responsible for the technical message handling to the different market partners The light gray boxes reflect the standard IDE Data Exchange framework which will still be used in the Process and Data-Exchange Framework Solution Process and Data-Exchange Framework for Utilities Release 1.0 SAP Enhancement Package Enhancement Packages 4,5 and 6 Based On BI Content-Release SAP Utilities Not applicable Components: Process and Data-Exchange Framework Main components are: Process Configuration Layer A process is by definition a directed (oriented) graph consisting of nodes and arrows. The set of nodes is represented by the set of elementary process steps. Each process consists of a number of process steps which correspond to market messages or activities which have occurred within the processes (and which should trigger a further processing). Process steps can be executed automatically by the Process Engine when determining the next possible steps or if it s a manual step then it will be executed externally without Process engine. Process arrows link all process steps of a process such that the process becomes an oriented graph. Process arrows will also link the process step of one process step of another process for inter process linkage. Process Execution Layer When the Process Engine is called it will check for processes that are ready to be processed and triggers them. This layer also contains the process instances represented by their associated configuration layer (process classes and their associated process steps D Walldorf Page 9 of 21

10 represented by process step classes). Once a process is triggered by the Process Engine it will determine and execute all process steps that are ready to be processed. Per each (successfully) executed process step the process instance will again determine and execute all process steps that are ready to be processed. Thus the process instances will traverse the process graph until all process steps currently available for processing have been executed Process UI Layer The standard Switch Document has been enhanced to become more generic Process Document. The user can see: Current status of the overall process Relevant information depending on type of process All activities Messages that have been sent and received Data content of the messages depending on type of message Errors that have occurred and exceptions that have been created Process steps which have been executed and their individual status Linked processes either as parent/link or associated link. Check Framework The check framework is an enhancement of the standard SAP Intercompany Data Exchange (IDE)check framework with following additional features: Definition and allocation of check groups to check applications, allowing for adding and deleting checks through customizing Ability to be called from anywhere Flexible interface definition allowing the implementation Project to define their own checks Period Framework This is a framework to ensure that all scheduled process steps are carried out at the appropriate time. Since no SAP Business Workflow will be used, a new deadline monitoring report will be made available. The definition of deadlines is based on the standard SAP/IDE period management Exception Framework Any kind of errors or exceptions will be handled through the standard BPEM tool. This can also be called from other systems, like SAP PI. For easier use the framework provides additional functionality: Customizing to define exception codes and the corresponding BPEM case category Default implementation of a BADI reading and interpreting the customizing and for creation of a BPEM case Predefined exception resolution possibilities (handling alternatives), including D Walldorf Page 10 of 21

11 Reprocessing of process step Set inbound message to obsolete and act as if it has not been received; continue waiting for the same message Resend outbound message again with new message data collection Resend outbound message again as is (technical resend) End processing of current process Intercompany Data Exchange (IDE) Layer This component describes the processing of sending and receiving messages. It is based on the standard IDE Infrastructure with an additional Message Mapping Framework: Adding predefined metadata structures Predefined architecture of OO objects (class hierarchy) for uniform and easy to maintain development of required mappings For further details on architecture, refer to High Level Solution Proposal document for IDEX infrastructure from SAP Custom Development.

12 Evolution Process and Data-Exchange Solution in its current form (RCS: Framework + RCS: Country specific solution (if exists) + Customer specific implementation) is a result of evolution through various IDEX Custom Development projects in Europe/Asia over past 6 years. The significant improvements up to now are: Workflow replaced with efficient Process modelling tool Central Process Engine with segregation of process steps into basic categories and corresponding methods/interfaces Improved flexible UI interface The following chart shows evolution of the solution from one Custom Development Project to next. This chart only shows CDPs which had significant impact on development of Process and Data-Exchange Solution as it is now. Figure 4: Evolution chart D Walldorf Page 12 of 21

13 Evolutionary Benefits This section highlights those areas of change through out the lifecycle of the IDEX solution and explains how the change has benefited the solution. Area Workflow Benefit of Change Initially the IDEX solution was a workflow based solution, over the lifetime of the solution the use of SAP standard workflow was reduced to a limited use for the npower solution and finally removed with the Iberdrola Scottish Power implementation. The benefit this has brought is that whilst it is possible to have a specific version of a process all changes made to the configuration of that process are actioned in real time meaning that all in flight processes are working on the same platform. With the SAP workflow approach it was likely that industry lead processes were not working to the same industry or business current requirement. Switch Document The first IDEX solutions centred on Data Exchange to support switching processes (Customer Loss and Gain). With the npower solution the switch document was further enhanced to support other Supplier/Retailer industry processes such as Device exchange, Device inspections etc. This gave the first UI representation of a business industry process in an easy to read step format. With the Iberdrola Scottish Power implementation this was further enhanced to support other market roles such as Data Collector and Meter Asset Manager. Flexibility Customizing The following list provides a short overview of the available customizing options: Process Configuration/ Monitoring Process Configuration Scenario Period type configuration for Hour/Minute/Second Process Monitoring configuration Check Framework configuration Configuration of Response Codes Master data configuration with corresponding Outcomes D Walldorf Page 13 of 21
