Search Results inv.mtl_material_transactions




The INV.MTL_MATERIAL_TRANSACTIONS table is a fundamental data structure within Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2, specifically in the Inventory (INV) module. It serves as the primary repository for recording all material transactions, capturing movements of items across organizations, subinventories, and locations. This table is critical for maintaining inventory accuracy, supporting cost accounting, and enabling traceability of item movements throughout the supply chain.

Key Attributes and Structure

The table contains numerous columns that document transactional details, including:
  • TRANSACTION_ID: Primary key, uniquely identifying each transaction.
  • INVENTORY_ITEM_ID: Links to MTL_SYSTEM_ITEMS_B to identify the item involved.
  • ORGANIZATION_ID: Specifies the inventory organization where the transaction occurred.
  • TRANSACTION_TYPE_ID: References MTL_TRANSACTION_TYPES to classify the transaction (e.g., Issue, Receipt, Transfer).
  • TRANSACTION_QUANTITY: Records the quantity of items moved.
  • TRANSACTION_UOM: Unit of measure for the transaction.
  • SUBINVENTORY_CODE: Identifies the source or destination subinventory.
  • LOCATOR_ID: Tracks the specific locator within a subinventory.
  • TRANSACTION_DATE: Timestamp of the transaction.
  • COSTED_FLAG: Indicates whether the transaction has been cost-processed.
  • SOURCE_CODE: Identifies the originating module (e.g., "Purchasing" for PO receipts).

Functional Role in Oracle EBS

The table integrates with multiple EBS modules, including Purchasing (PO), Order Management (OM), Work in Process (WIP), and Cost Management (CST). For example:
  • Purchasing: Records receipts against purchase orders.
  • Order Management: Tracks shipments and returns linked to sales orders.
  • Work in Process: Logs component issues and assembly completions.
  • Cost Management: Provides data for calculating inventory valuations and COGS.

Technical Considerations

  • Performance: The table can grow rapidly in high-volume environments, necessitating partitioning or archival strategies.
  • Indexing: Key indexes include MTL_MATERIAL_TRANSACTIONS_N1 (TRANSACTION_ID) and MTL_MATERIAL_TRANSACTIONS_N2 (INVENTORY_ITEM_ID, ORGANIZATION_ID).
  • Concurrency: Oracle employs row-level locking during transaction posting to ensure data integrity.

Integration Points

The table feeds downstream processes such as:
  • GL_INTERFACE: For financial posting of inventory values.
  • CST_COST_DISTRIBUTION_LINES: For cost absorption calculations.
  • MTL_ONHAND_QUANTITIES: Updates on-hand balances in real-time.

Customization and Extensions

Organizations often extend functionality through:
  • Custom triggers to enforce business rules during transactions.
  • API-based integrations (INV_TRANSACTION_MANAGER_PUB) for automated postings.
  • Views layered atop the table for reporting purposes.

Audit and Compliance

The table supports regulatory requirements by:
  • Maintaining a complete audit trail of material movements.
  • Storing reference documents (e.g., PO numbers, sales order lines).
  • Enabling lot/serial traceability through linked tables like MTL_SERIAL_NUMBERS_INTERFACE.
In summary, INV.MTL_MATERIAL_TRANSACTIONS forms the operational backbone of inventory management in Oracle EBS, bridging transactional execution with financial and analytical reporting. Its design reflects Oracle's commitment to supporting complex manufacturing, distribution, and retail operations while maintaining rigorous data integrity standards.
