The HR_H2PI_DATA_FEED_HIST table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical component of the Human Resources (HR) module, specifically designed to support the H2PI (HR to Payroll Interface) data feed history. This table stores historical records of data transfers between the HR and Payroll modules, ensuring traceability, auditability, and compliance with data integration requirements. Below is a detailed analysis of its structure, purpose, and functional significance in Oracle EBS.

Purpose and Functional Context

The HR_H2PI_DATA_FEED_HIST table serves as a repository for historical data feeds generated during the HR-to-Payroll integration process. In Oracle EBS, the H2PI interface facilitates the seamless transfer of employee-related data (e.g., salary changes, deductions, benefits, and tax information) from the HR module to the Payroll module. This ensures payroll processing is based on the most up-to-date employee records. The historical feed stored in this table allows administrators to track changes, troubleshoot discrepancies, and maintain compliance with regulatory requirements.

Key Columns and Data Structure

The table typically includes the following key columns:
  • FEED_ID: A unique identifier for each data feed record.
  • EMPLOYEE_ID: References the employee for whom the data feed was generated.
  • FEED_TYPE: Indicates the type of data transferred (e.g., salary update, deduction change).
  • FEED_DATE: The timestamp when the data feed was generated.
  • STATUS: Reflects the processing status (e.g., "Pending," "Processed," "Error").
  • PAYROLL_ID: Links to the payroll period for which the feed was intended.
  • ERROR_MESSAGE: Captures any errors encountered during processing.
  • CREATED_BY and LAST_UPDATED_BY: Audit columns tracking user actions.

Integration with Other Modules

The HR_H2PI_DATA_FEED_HIST table interacts closely with:
  • HRMS Base Tables: Such as PER_ALL_PEOPLE_F (employee data) and PER_ALL_ASSIGNMENTS_F (assignment details).
  • Payroll Tables: Like PAY_ALL_PAYROLLS_F (payroll definitions) and PAY_ASSIGNMENT_ACTIONS (payroll processing logs).
  • Interface Tables: Such as HR_H2PI_DATA_FEED (active feed records before archival).

Technical and Business Significance

  1. Data Integrity: Ensures payroll calculations are based on accurate HR data by maintaining a historical trail.
  2. Audit Compliance: Supports regulatory audits by providing a timestamped record of changes.
  3. Error Resolution: Enables quick identification and correction of failed data transfers.
  4. Performance Optimization: By archiving processed feeds, it reduces the volume of active data in operational tables.

Customization and Extensions

In implementations where additional data points are required for payroll processing, custom columns or related tables may be added. However, caution is advised to avoid conflicts with Oracle's upgrade scripts. Reports leveraging this table often use Oracle BI Publisher or custom SQL queries to analyze feed trends or error rates.

Conclusion

The HR_H2PI_DATA_FEED_HIST table is a foundational element in Oracle EBS HR-Payroll integration, providing historical transparency and operational reliability. Its design aligns with Oracle's best practices for data segregation and auditability, making it indispensable for organizations requiring robust payroll processing controls in versions 12.1.1 and 12.2.2.
