The file ONT_Tables.html pertains to the Oracle Order Management (OM) module within Oracle E-Business Suite (EBS) versions 12.1.1 or 12.2.2. This document typically serves as a technical reference, detailing the database tables associated with the ONT (Order Entry) schema, which is a core component of Oracle OM. Below is a structured summary of its key aspects in the context of Oracle EBS:

1. Purpose and Scope

The ONT_Tables.html file provides a comprehensive list of tables used by the Oracle Order Management module, including their structures, relationships, and primary functionalities. These tables store critical data such as sales orders, order lines, pricing, shipping, and fulfillment details. The document is essential for developers, functional consultants, and DBAs working on customizations, integrations, or performance tuning in Oracle EBS.

2. Key Tables in the ONT Schema

The ONT schema includes several pivotal tables, such as:
  • OE_ORDER_HEADERS_ALL: Stores header-level information for sales orders, including order number, customer details, and status.
  • OE_ORDER_LINES_ALL: Contains line-level details like items, quantities, pricing, and shipping information.
  • OE_TRANSACTION_TYPES_TL: Defines order transaction types (e.g., Sales Order, Return).
  • OE_PRICE_ADJUSTMENTS: Manages pricing adjustments, discounts, and promotions applied to orders.
  • OE_HOLD_SOURCES: Tracks order holds and their sources.
  • OE_SALES_CREDITS: Assigns sales credits to orders for commission tracking.

3. Integration with Other EBS Modules

The ONT tables integrate with multiple Oracle EBS modules, including:
  • Inventory (INV): For item availability and shipping.
  • Accounts Receivable (AR): For invoicing and customer data.
  • Advanced Pricing (QP): For pricing rules and adjustments.
  • Shipping Execution (WSH): For shipment scheduling and tracking.

4. Technical Considerations

In Oracle EBS 12.1.1 and 12.2.2, the ONT tables follow these technical patterns:
  • Multi-Org Structure: Tables like OE_ORDER_HEADERS_ALL use the _ALL suffix to support multi-org access control (MOAC).
  • Foreign Key Relationships: Tables are linked via keys like HEADER_ID (between headers and lines) or INVENTORY_ITEM_ID (for items).
  • Indexing: Critical columns (e.g., ORDER_NUMBER, CUSTOMER_ID) are indexed for performance.

5. Customization and Extensions

The ONT_Tables.html file aids in:
  • Custom Reports: Querying tables like OE_ORDER_LINES_ALL for order analytics.
  • Workflows: Extending order approval processes using PL/SQL triggers on ONT tables.
  • Data Migrations: Mapping legacy data to ONT tables during EBS implementations.

6. Version-Specific Differences

Between EBS 12.1.1 and 12.2.2, changes to ONT tables may include:
  • New Columns: Added in 12.2.2 for enhanced functionality (e.g., cloud integration fields).
  • Deprecated Features: Older columns or tables flagged for removal.
  • Performance Optimizations: Partitioning or indexing improvements in 12.2.2.

Conclusion

The ONT_Tables.html file is a vital resource for understanding the data model of Oracle Order Management in EBS 12.1.1 and 12.2.2. It enables efficient development, troubleshooting, and optimization of order-related processes while ensuring seamless integration with other EBS modules. Consultants and developers should refer to this document when designing custom solutions or upgrading between EBS versions.
