Utility ERP & CIS glossary
This glossary defines the Oracle Utilities and SAP terms that appear most often in utility CIS and ERP programs, from meter-to-cash and AMI through to the specific product names and framework components teams hire against.
Written for utility IT leaders, program managers and hiring teams who need the vocabulary to be precise.
Definitions
Alphabetized terms used across utility customer information and enterprise asset programs.
- AMI (Advanced Metering Infrastructure)
- AMI is the combination of smart meters, communications network and head-end software that lets a utility collect interval consumption data remotely instead of sending a meter reader. It produces readings at typically 5-, 15-, 30- or 60-minute intervals depending on the meter and the program, along with events and alarms such as outage and tamper notifications. AMI is what turns a monthly register read into millions of daily data points, which is why meter data management became a distinct system.
- C2M (Customer to Meter)
- Oracle's converged product that merges Customer Care and Billing with Meter Data Management into a single codebase and application instance. Usage transactions flow internally from meter data processing into billing rather than across an integration layer, and the two functions share one upgrade cycle, security model and configuration environment. Oracle C2M staffing.
- CC&B (Customer Care and Billing)
- Oracle Utilities Customer Care and Billing is the standalone customer information system that runs meter-to-cash for many utilities. It holds the customer, account, premise and service point data model, calculates charges from rate configuration, issues bills on cycle, applies payments and manages credit and collections. It is built on the Oracle Utilities Application Framework. Oracle CC&B staffing.
- CCS (Customer Cloud Service)
- Oracle's software-as-a-service delivery of the converged customer and meter product. Oracle hosts the environments, applies patches and delivers releases on a regular cadence, so the utility no longer manages infrastructure or chooses upgrade timing. Configuration and supported extension mechanisms are favored over deep customization. Oracle CCS staffing.
- CIS (Customer Information System)
- The system of record for a utility's customer relationships and revenue cycle: who the customer is, what service they take at which premise, what they are charged, what they have paid and what they owe. A CIS is also the application the call center works in, so it sits at the intersection of finance, regulatory compliance and customer experience.
- Device Management
- In SAP IS-U, the functional area covering technical master data and field activity for meters and related equipment: device categories, installation and removal, device modification, register configuration, and the creation and processing of meter reading orders and results. Reads are validated here before they reach billing.
- EDM (Energy Data Management)
- The SAP IS-U component that handles interval and profile data rather than simple register readings. It supports profile allocation, synthetic and analytical profiles, formula-based derivation and settlement-relevant data preparation. EDM is where AMI-driven interval consumption is validated and made billable.
- FI-CA (Contract Accounts Receivable and Payable)
- SAP's high-volume receivables subledger, used for utility customer accounts. It manages contract accounts, payment processing and clearing, dunning and collections strategies, installment plans, security deposits, interest and write-offs, then posts summarized entries to the general ledger. Most revenue reconciliation issues on an IS-U program surface in FI-CA.
- Head-end system
- The software that communicates directly with meters over the AMI network: it commissions devices, collects reads and events, and executes on-demand commands such as a remote disconnect or ping. The head-end is metering infrastructure, not a billing system; it hands data onward to meter data management through an adapter layer such as Smart Grid Gateway.
- IS-U (Industry Solution for Utilities)
- SAP's utility customer information and billing solution, running inside the SAP ERP stack. It covers device management, meter reading, billing and invoicing, energy data management and FI-CA. Because it shares SAP's finance and master data foundation, the revenue cycle and general ledger sit on one platform. SAP IS-U staffing.
- MDM (Meter Data Management)
- The system that receives raw interval and register data from head-end systems, validates and corrects it, and converts it into billable usage. Its core responsibilities are the VEE rule set, storage of the interval history, and usage transaction calculation. In Oracle's converged products this function lives inside C2M and CCS rather than in a separate instance. Oracle MDM staffing.
- Meter-to-cash
- The end-to-end utility revenue process: reading or collecting consumption, validating it, calculating charges from rate configuration, issuing the bill, receiving and applying payment, and pursuing arrears through credit and collections. Almost every role on a utility CIS program is defined by which part of meter-to-cash it touches.
- NMS (Network Management System)
- Oracle Utilities Network Management System is the operational platform for the electric distribution network. It maintains a connectivity model of the network and supports outage management, switching, crew dispatch, restoration estimation and distribution operations. It works from real-time network state rather than customer billing data. Oracle NMS staffing.
- OMS (Outage Management System)
- The capability that detects, groups and tracks outages: it correlates customer calls, AMI last-gasp events and SCADA telemetry to predict the failed device, then manages crew assignment, restoration steps and customer-facing estimated restoration times. In the Oracle stack, outage management is delivered as part of NMS.
- ORMB (Oracle Revenue Management and Billing)
- A billing and revenue management platform for complex, high-volume commercial pricing, used in utilities and in financial services and healthcare. It handles sophisticated pricing hierarchies, agreements, deals and consolidated invoicing that go beyond standard tariff-based residential billing. It shares the Oracle Utilities Application Framework with CC&B. Oracle ORMB staffing.
- OUAF (Oracle Utilities Application Framework)
- The shared technical foundation beneath CC&B, C2M, MDM, WAM, ORMB and related products. It provides the maintenance object and business object model, algorithms, scripting, batch processing, service and inbound web service definitions, security and the configuration tooling. Anyone extending an Oracle Utilities product works in OUAF, which is why OUAF skills transfer across the product family. OUAF developer staffing.
- SGG (Smart Grid Gateway)
- The Oracle Utilities adapter layer between head-end systems and meter data management. It normalizes vendor-specific meter data formats into the standard model, and carries commands in the other direction: device commissioning, on-demand reads, remote connect and disconnect. Utilities with multiple meter vendors typically run multiple SGG adapters.
- Usage transaction
- The bridge between meter data and billing. A usage transaction requests consumption for a service point and billing period, applies the configured usage rules to the validated interval or register data, and returns the quantities billing will price. When a bill looks wrong on AMI-served accounts, the usage transaction is usually the first place to look.
- VEE (Validation, Estimation and Editing)
- The rule framework in meter data management that decides whether measurement data is trustworthy and what to do when it is not. Validation checks for gaps, spikes, negative or out-of-tolerance values; estimation fills missing intervals using configured methods; editing records any corrections with an audit trail. VEE configuration directly determines billing accuracy and exception volume.
- WACS (Work and Asset Cloud Service)
- The Oracle-managed cloud delivery of Work and Asset Management. Functionally aligned with WAM, it shifts infrastructure, patching and release delivery to Oracle, with configuration and supported extension favored over heavy customization.
- WAM (Work and Asset Management)
- Oracle Utilities Work and Asset Management maintains the asset registry and asset hierarchy and runs the work that keeps assets serviceable: preventive maintenance schedules, work orders and activities, inspections, storeroom and inventory, and purchasing. It is the operational counterpart to the customer-facing CIS. Oracle WAM staffing.
