Overview

The CS_CTR_ESTIMATED_READINGS table is a core data structure within the Oracle E-Business Suite Service (CS) module, specifically designed to manage estimated meter readings. In service contracts and field service operations, accurate tracking of equipment usage via meters is critical for billing, maintenance scheduling, and contract fulfillment. When an actual physical reading cannot be obtained, the system generates an estimated reading. This table serves as the central repository for storing these calculated estimates, ensuring continuity in meter history and supporting automated processes like billing and service level agreement (SLA) monitoring. Its role is integral to the meter reading and estimation engine of Oracle EBS, maintaining data integrity between actual readings and forecasted usage.

Key Information Stored

The table's primary purpose is to record the details of each generated estimate. While the full column list is not provided in the excerpt, the documented primary and foreign keys reveal its critical data elements. The ESTIMATED_READING_ID column is the unique identifier (primary key) for each estimated reading record. The ESTIMATION_ID column is a foreign key that links each estimated reading to its source method in the CS_CTR_ESTIMATION_METHODS table. This relationship is crucial for auditability, indicating which estimation algorithm or rule was applied. Typically, such a table would also store columns for the estimated reading value, the date/time of the estimate, the meter ID for which the estimate was created, and the period the estimate covers.

Common Use Cases and Queries

This table is primarily accessed for operational reporting, discrepancy analysis, and audit trails. Common scenarios include reviewing all estimates generated for a specific meter over a period, comparing estimated values to subsequently entered actual readings to calibrate estimation methods, and generating reports for customer billing disputes. A typical query would join this table to meter and customer information.

  • Finding Estimates for a Meter: SELECT * FROM cs_ctr_estimated_readings WHERE meter_id = :p_meter_id ORDER BY estimate_date;
  • Auditing Estimation Method Usage: SELECT e.estimation_method_name, COUNT(*) FROM cs_ctr_estimated_readings r, cs_ctr_estimation_methods e WHERE r.estimation_id = e.estimation_id GROUP BY e.estimation_method_name;

Related Objects

The table maintains defined relationships with other key Service module tables, as per the provided foreign key metadata.

  • CS_CTR_ESTIMATION_METHODS: This is the primary related table. Each record in CS_CTR_ESTIMATED_READINGS must reference a valid estimation method via the ESTIMATION_ID column (CS_CTR_ESTIMATED_READINGS.ESTIMATION_ID -> CS_CTR_ESTIMATION_METHODS). This defines the logic used to create the estimate.
  • In a full implementation, this table would also have foreign key relationships to core meter and service point tables (e.g., CS_METERS_B, CS_SERVICE_POINTS) to identify the asset being measured, though these are not explicitly listed in the provided excerpt.
