The ENG.ENG_ECO_SUBMIT_REVISIONS table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Engineering Change Order (ECO) module, which is part of the Oracle Engineering suite. This table plays a pivotal role in managing and tracking revisions submitted for engineering change orders, ensuring that modifications to product designs, bills of materials (BOMs), and routings are systematically controlled and audited. Below is a detailed analysis of its purpose, structure, and functional significance in Oracle EBS.

Purpose and Functional Context

The ENG.ENG_ECO_SUBMIT_REVISIONS table stores metadata related to revision submissions for engineering change orders. ECOs are formal mechanisms used to propose, review, approve, and implement changes to product designs or manufacturing processes. This table specifically captures the revision history of submitted ECOs, enabling traceability and compliance with change management protocols. It acts as a junction between the ECO header information (stored in tables like ENG.ENG_ENGINEERING_CHANGES) and the detailed revision data, ensuring that each change request is documented with timestamps, statuses, and submitter details.

Key Columns and Data Structure

While the exact schema may vary slightly between EBS 12.1.1 and 12.2.2, the table typically includes the following columns:
  • CHANGE_ID: Foreign key linking to the parent ECO in ENG.ENG_ENGINEERING_CHANGES.
  • REVISION_ID: Unique identifier for each revision submission.
  • SUBMIT_DATE: Timestamp when the revision was submitted.
  • SUBMIT_BY: User ID or reference of the submitter (often linked to FND_USER).
  • STATUS: Current state of the revision (e.g., "Pending," "Approved," "Rejected").
  • APPROVAL_PATH_ID: Reference to the workflow approval path (if applicable).
  • DESCRIPTION: Free-text field for revision notes or rationale.
  • ATTRIBUTE_CATEGORY and ATTRIBUTE_n: Flexfields for custom attributes.

Integration with ECO Workflow

The table integrates with Oracle EBS's workflow engine to automate approval processes. When a revision is submitted, records in ENG.ENG_ECO_SUBMIT_REVISIONS trigger notifications to approvers, and status updates are reflected in real-time. This ensures alignment with organizational policies and audit requirements. The table's data is often accessed by ECO workflow APIs (e.g., ENG_ECO_PUB) to enforce business rules during submission or approval.

Reporting and Auditing

Data from this table is leveraged for compliance reporting and historical tracking. Standard Oracle reports, such as the "ECO Revision History Report," join this table with ENG.ENG_ENGINEERING_CHANGES to provide a comprehensive view of change timelines. Additionally, audit trails are maintained for regulatory purposes (e.g., ISO 9001), where revision timestamps and submitter details are critical.

Technical Considerations

In EBS 12.2.2, the table may leverage Oracle's Online Patch (OLP) and Edition-Based Redefinition (EBR) features for zero-downtime upgrades. Performance optimizations, such as indexing on CHANGE_ID and REVISION_ID, are recommended for large-scale implementations. Customizations should avoid direct DML on this table, using Oracle's public APIs instead to maintain data integrity.

Conclusion

The ENG.ENG_ECO_SUBMIT_REVISIONS table is a foundational component of Oracle EBS's Engineering Change Management functionality. It ensures structured control over product design revisions, supports automated workflows, and provides auditable records for compliance. Understanding its schema and integration points is essential for implementing robust change management processes in manufacturing and product lifecycle environments.
