Overview

The table CST_EAM_ASSET_PER_BALANCES is a core data structure within the Oracle E-Business Suite (EBS) Bills of Material (BOM) module, specifically supporting Enterprise Asset Management (EAM) costing functionality. Its primary role is to store detailed, periodic cost information for individual, serialized assets. This table acts as a ledger, capturing the accumulation of maintenance and repair costs over time, which is essential for calculating total asset ownership costs, performing lifecycle cost analysis, and supporting accurate financial reporting for capital assets managed within the EAM framework.

Key Information Stored

While the provided ETRM metadata does not list specific columns, the table's description and foreign key relationships define its critical data elements. It stores cost balances linked to a unique asset identifier, which is a combination of INVENTORY_ITEM_ID, SERIAL_NUMBER, and ORGANIZATION_ID. Each record is further categorized by a MAINT_COST_CATEGORY, allowing costs to be broken down by type (e.g., labor, material, overhead). The table likely contains period-specific columns (e.g., PERIOD_ID, PERIOD_YEAR) and numeric columns to hold the actual cost amounts (e.g., PERIOD_DEBIT, PERIOD_CREDIT, PERIOD_NET, CUMULATIVE_COST). This structure enables tracking of both period-specific and year-to-date cost transactions for each asset and cost category.

Common Use Cases and Queries

This table is central to EAM asset cost reporting and reconciliation. Common use cases include generating asset valuation reports, analyzing maintenance spend by cost category, and reconciling EAM work order costs to the general ledger. A typical analytical query would join this table to asset and cost element master data. For example, to retrieve the cumulative maintenance cost for a specific asset serial number, one might use a pattern such as:

  • SELECT msn.serial_number, cece.cost_element, csum.cumulative_cost
  • FROM bom.cst_eam_asset_per_balances csum
  • JOIN inv.mtl_serial_numbers msn ON msn.serial_number = csum.serial_number AND msn.inventory_item_id = csum.inventory_item_id AND msn.current_organization_id = csum.organization_id
  • JOIN bom.cst_eam_cost_elements cece ON cece.cost_element = csum.maint_cost_category
  • WHERE csum.serial_number = '<SERIAL>' AND csum.period_year = '<YEAR>';

Related Objects

CST_EAM_ASSET_PER_BALANCES is integrally linked to master data tables via documented foreign key constraints. The primary relationships are:

  • MTL_SERIAL_NUMBERS: The table validates the asset's existence through a composite foreign key on the columns SERIAL_NUMBER, INVENTORY_ITEM_ID, and ORGANIZATION_ID. This ensures every cost record corresponds to a tangible, serialized item in inventory.
  • CST_EAM_COST_ELEMENTS: The table validates the cost category via a foreign key on the MAINT_COST_CATEGORY column. This ensures all categorized costs align with predefined EAM cost elements configured within the application.

This table is also a likely source for various EAM cost summary views and is populated by transaction processors from EAM work order completion and material issue transactions.
