DeepseekETRM - EAM Tables and Views in Oracle EBS 12.1.1 & 12.2.2

Overview

DeepseekETRM (Enterprise Asset Management Technical Reference Manual) provides a comprehensive repository of tables and views used in Oracle Enterprise Asset Management (EAM) modules for Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2. EAM facilitates asset lifecycle management, maintenance operations, and resource planning. Understanding its underlying database structure is critical for customization, reporting, and integration.

Key EAM Tables

1. WIP_EAM_ASSET_ACTIVITIES (EAM Asset Activities)
Stores asset maintenance activities, including work orders, labor, and material requirements. Key columns: WIP_ENTITY_ID, ACTIVITY_TYPE_CODE, ASSET_NUMBER, ACTIVITY_CAUSE_CODE. 2. EAM_ASSET_NUMBERS (Asset Master)
Core table for asset registration, tracking asset attributes like location, status, and hierarchy. Key columns: ASSET_NUMBER, ORGANIZATION_ID, PARENT_ASSET_ID, INSTALL_DATE. 3. WIP_EAM_WORK_ORDERS (Work Orders)
Manages work order details, including priority, scheduling, and labor assignments. Key columns: WIP_ENTITY_ID, ORGANIZATION_ID, STATUS_TYPE, SCHEDULED_START_DATE. 4. EAM_METER_READINGS (Meter Readings)
Tracks usage-based maintenance triggers (e.g., equipment runtime). Key columns: METER_ID, ASSET_NUMBER, READING_VALUE, READING_DATE. 5. EAM_ROUTINES (Maintenance Routines)
Defines preventive maintenance schedules. Key columns: ROUTINE_ID, FREQUENCY, LAST_WO_CREATED.

Key EAM Views

1. EAM_ASSET_V (Asset Master View)
Consolidates asset data from multiple tables for reporting. Includes fields like ASSET_DESCRIPTION, CURRENT_LOCATION, and ACTIVE_FLAG. 2. EAM_WO_DETAILS_V (Work Order Details)
Aggregates work order data with labor, materials, and asset info. Key columns: WO_NUMBER, ASSET_DESCRIPTION, TOTAL_COST. 3. EAM_METER_READINGS_V (Meter Readings View)
Joins meter data with asset details for trend analysis. Includes METER_NAME, UOM, and threshold comparisons.

Technical Considerations

  • Schema Ownership: Most EAM tables reside in APPS schema with synonyms for modular access.
  • Integration Points: Tables link to Inventory (INV), Work in Process (WIP), and GL modules via ORGANIZATION_ID, INVENTORY_ITEM_ID.
  • Indexing: Critical for performance on large datasets (e.g., WIP_ENTITY_ID, ASSET_NUMBER).
  • Custom Extensions: Custom columns should use descriptive naming (e.g., XX_CUSTOM_FIELD) to avoid upgrade conflicts.

Version-Specific Notes

12.2.2 Enhancements:
  • Added support for IoT integrations in EAM_METER_READINGS.
  • New views for mobile EAM workflows (EAM_MOBILE_WO_V).
  • Extended asset hierarchy depth in EAM_ASSET_NUMBERS.

Best Practices

  1. Use views for reporting to abstract underlying table changes.
  2. Leverage Oracle's EAM APIs for data modifications to maintain integrity.
  3. Audit performance-impacting queries on large tables like WIP_EAM_WORK_ORDERS.
