The GML_GASNO_DETAIL_ALLOCATIONS table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical data structure within the Global Trade Management (GTM) module, specifically designed to manage and track gas allocation details. This table plays a pivotal role in industries where gas allocation and distribution are key operational components, such as oil and gas, utilities, and energy sectors. Below is a detailed technical and functional breakdown of this table.

1. Table Purpose and Functional Context

The GML_GASNO_DETAIL_ALLOCATIONS table stores granular data related to gas allocation transactions. It is part of Oracle's Gas Nomination (GASNO) functionality, which facilitates the scheduling, tracking, and reconciliation of gas nominations between suppliers, transporters, and customers. Key business processes supported include:
  • Nomination Management: Captures detailed allocation records for gas quantities nominated by parties.
  • Reconciliation: Trades, contracts, and delivery points.
  • Regulatory Compliance: Ensures adherence to industry standards and reporting requirements.

2. Key Columns and Data Structure

The table's schema includes columns to track transactional, contractual, and operational attributes. Notable columns may include:
  • ALLOCATION_ID: Primary key uniquely identifying each allocation record.
  • GASNO_HEADER_ID: Foreign key linking to the parent nomination header (GML_GASNO_HEADERS).
  • CONTRACT_ID: References the contract governing the allocation.
  • QUANTITY: Allocated gas volume (e.g., in MMBtu or cubic meters).
  • UOM_CODE: Unit of measure (e.g., MCF, GJ).
  • START_DATE/END_DATE: Validity period of the allocation.
  • STATUS: Lifecycle state (e.g., "Draft," "Approved," "Cancelled").
  • CREATED_BY/CREATION_DATE: Audit columns for tracking record creation.

3. Integration with Other Modules

The table integrates with core EBS modules:
  • Inventory (INV): Links to gas stock movements and storage locations.
  • Order Management (OM): Aligns allocations with customer orders.
  • General Ledger (GL): Supports financial posting of allocation transactions.

4. Technical Considerations

  • Indexing: Typically indexed on ALLOCATION_ID, GASNO_HEADER_ID, and CONTRACT_ID for performance.
  • Partitioning: May be partitioned by date ranges in high-volume environments.
  • API Access: Oracle provides PL/SQL APIs (e.g., GML_GASNO_PUB) to manipulate data programmatically.

5. Customization and Extensions

Organizations often extend this table to include:
  • Custom fields for regulatory reporting (e.g., EPA codes).
  • Integration with third-party logistics systems.
  • Workflow enhancements for approval routing.

6. Data Lifecycle and Maintenance

  • Archiving: Historical allocations may be purged or archived to optimize performance.
  • Audit Trails: Changes are logged in audit tables (e.g., GML_GASNO_ALLOC_AUDIT).

7. Upgrade Implications

Between EBS 12.1.1 and 12.2.2, schema changes are minimal, but enhancements may include:
  • Improved validation logic.
  • Additional columns for cloud integration.
  • Performance optimizations in concurrent processing.

Conclusion

The GML_GASNO_DETAIL_ALLOCATIONS table is a cornerstone of gas nomination management in Oracle EBS, enabling precise tracking, compliance, and operational efficiency. Its design reflects Oracle's commitment to industry-specific functionality while maintaining integration with broader EBS ecosystems. For implementations in regulated industries, understanding this table's structure and behavior is essential for successful system configuration and customization.
