The PO_MULTI_MOD_VAL_RESULTS table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical repository for storing validation results generated during the processing of multi-module purchase order (PO) transactions. This table plays a pivotal role in ensuring data integrity and compliance with business rules when POs interact with multiple modules, such as Inventory, Payables, and General Ledger. Below is a detailed analysis of its structure, purpose, and functional significance.

Table Overview

The PO_MULTI_MOD_VAL_RESULTS table is part of the Purchasing (PO) module and is designed to capture validation outcomes when POs are submitted, approved, or modified across integrated modules. It acts as a log for error messages, warnings, or success notifications generated during cross-module validations. Key attributes of this table include:
  • VALIDATION_ID: A unique identifier for each validation result entry.
  • PO_HEADER_ID and PO_LINE_ID: References to the PO header and line being validated.
  • MODULE_CODE: Indicates the module (e.g., INV for Inventory, AP for Payables) involved in the validation.
  • VALIDATION_TYPE: Classifies the validation as an error, warning, or informational message.
  • MESSAGE_TEXT: Detailed description of the validation outcome.
  • CREATION_DATE and CREATED_BY: Audit columns tracking when and by whom the record was created.

Functional Role

This table supports complex PO workflows by:
  1. Cross-Module Validation: Ensures POs comply with rules enforced by other modules (e.g., inventory item validity, account combinations).
  2. Error Handling: Captures validation failures (e.g., mismatched item categories, invalid GL dates) for corrective action.
  3. Audit Trail: Provides a historical record of validations for troubleshooting and compliance.

Integration Scenarios

Examples of its usage include:
  • Inventory Integration: Validates item attributes (e.g., stockable, purchasable) against MTL_SYSTEM_ITEMS.
  • Payables Integration: Checks vendor-site associations and payment terms alignment.
  • GL Integration: Verifies account segments and period statuses.

Technical Considerations

  • Indexing: Typically indexed on PO_HEADER_ID, PO_LINE_ID, and MODULE_CODE for performance.
  • Purge Mechanisms: Records may be archived or purged via concurrent programs to manage table growth.
  • API Dependencies: Often accessed via Oracle's PL/SQL APIs (e.g., PO_VALIDATIONS_PVT).

Version-Specific Notes

In EBS 12.2.2, enhancements may include:
  • Additional columns for cloud integration or REST service validations.
  • Improved message localization support.

Conclusion

The PO_MULTI_MOD_VAL_RESULTS table is indispensable for maintaining data consistency in multi-module PO transactions. Its structured logging of validation outcomes ensures seamless interoperability between Purchasing and other EBS modules, reducing errors and enhancing operational efficiency. Administrators should monitor its growth and leverage its data for root-cause analysis in PO-related issues.
