The SO_HEADERS_INTERFACE_ALL table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 serves as a critical interface table for importing sales order header data into the Order Management module. This table acts as a staging area where external systems or data sources can insert records before they are validated and processed by the Order Management Open Interface (OMOI) program. Below is a detailed analysis of its structure, purpose, and usage within Oracle EBS.

Purpose and Functionality

The primary purpose of SO_HEADERS_INTERFACE_ALL is to facilitate the bulk import of sales order header information into Oracle Order Management. It allows organizations to integrate data from external sources, such as legacy systems, EDI transactions, or third-party applications, without direct insertion into production tables. The table stores raw order header data until the OMOI program validates and transfers it to the base tables (OE_ORDER_HEADERS_ALL and related entities).

Key Columns and Structure

The table contains columns that map to essential sales order attributes, including:
  • INTERFACE_HEADER_ID: Primary key, uniquely identifying each interface record.
  • ORDER_SOURCE_ID: References the source system (e.g., EDI, web store).
  • ORDER_NUMBER: Optional field for external order references.
  • ORDER_TYPE_ID: Links to the order type defined in OE_TRANSACTION_TYPES_TL.
  • ORDERED_DATE: The date the order was placed.
  • CUSTOMER_PO_NUMBER: Purchase order number from the customer.
  • SHIP_TO_ORG_ID and BILL_TO_ORG_ID: References to customer ship-to and bill-to locations.
  • STATUS_FLAG: Indicates processing status (P = Pending, E = Error, V = Validated).
  • CREATION_DATE and LAST_UPDATE_DATE: Audit columns for tracking record changes.

Integration with Order Management

Data flows through the following steps:
  1. Data Insertion: External systems populate SO_HEADERS_INTERFACE_ALL with order header data, optionally including related lines in SO_LINES_INTERFACE_ALL.
  2. Validation: The OMOI program (via concurrent request "Order Import") validates records against business rules, such as customer existence, item availability, and pricing.
  3. Processing: Valid records are transferred to base tables (OE_ORDER_HEADERS_ALL), while errors are flagged in the interface table for correction.

Multi-Org Support

The _ALL suffix denotes multi-org functionality, allowing data segregation by operating unit (ORG_ID). This enables shared service deployments where a single instance serves multiple legal entities.

Common Challenges and Best Practices

  • Data Quality: Ensure mandatory fields (e.g., ORDER_TYPE_ID, ORDERED_DATE) are populated to avoid validation failures.
  • Performance: For large data volumes, schedule OMOI during off-peak hours and consider batch processing.
  • Error Handling: Monitor the STATUS_FLAG and use OE_INTERFACE_ERRORS to diagnose issues.

Version-Specific Considerations

Both Oracle EBS 12.1.1 and 12.2.2 use similar structures for SO_HEADERS_INTERFACE_ALL, though 12.2.2 may include minor enhancements in validation logic or performance optimizations. Always verify column mappings when upgrading or integrating with external systems. In summary, SO_HEADERS_INTERFACE_ALL is a foundational component of Oracle Order Management's integration framework, enabling scalable and controlled order data ingestion while maintaining data integrity through rigorous validation.
