Search Results supplier contacts




The PO_VENDOR_CONTACTS_OBS table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Purchasing (PO) module, specifically designed to store vendor contact information. This table serves as an extension or observation layer for vendor contact details, often used to track historical or supplementary data related to supplier interactions. Below is a detailed analysis of its purpose, structure, and functional relevance in Oracle EBS.

Purpose and Functional Context

The PO_VENDOR_CONTACTS_OBS table operates within the broader vendor management framework of Oracle Purchasing. It complements the primary vendor contact table (PO_VENDOR_CONTACTS) by capturing additional observations, audit trails, or contextual notes about vendor contacts. This is particularly useful for compliance, reporting, and historical tracking, ensuring that changes or interactions with vendor representatives are logged systematically.

Table Structure and Key Columns

While the exact schema may vary slightly between EBS 12.1.1 and 12.2.2, the table typically includes the following key columns:
  • VENDOR_CONTACT_ID: Foreign key linking to the primary contact record in PO_VENDOR_CONTACTS.
  • OBSERVATION_TYPE: Categorizes the nature of the observation (e.g., 'COMMUNICATION_LOG', 'COMPLIANCE_NOTE').
  • OBSERVATION_TEXT: Free-text field for detailed notes or descriptions.
  • CREATED_BY and CREATION_DATE: Audit columns tracking record creation.
  • LAST_UPDATED_BY and LAST_UPDATE_DATE: Audit columns for modifications.
  • ATTRIBUTE_CATEGORY and ATTRIBUTE1-15: Flexfield columns for custom extensions.

Integration with Oracle EBS Modules

The table integrates with core Purchasing workflows, such as:
  • Supplier Management: Enhances vendor onboarding and maintenance by storing contact-related annotations.
  • Procurement Collaboration: Logs communication history for RFQs or purchase order negotiations.
  • Compliance and Auditing: Provides traceability for regulatory requirements (e.g., ISO standards, SOX).

Technical Considerations

  1. Performance: Indexes on VENDOR_CONTACT_ID and OBSERVATION_TYPE are recommended for query efficiency.
  2. Data Volume: Large-scale implementations may require partitioning or archiving strategies due to the observational nature of the data.
  3. Customization Flexfields enable industry-specific adaptations without schema changes.

Differences Between EBS 12.1.1 and 12.2.2

In EBS 12.2.2, enhancements may include:
  • Additional audit columns for Oracle's Online Patching (ADOP) framework.
  • Tighter integration with Oracle Supplier Network (OSN) for real-time contact updates.
  • Improved flexfield validation in line with 12.2's extensibility features.

Best Practices for Utilization

To maximize the table's utility:
  • Leverage it for non-transactional vendor data to avoid bloating primary tables.
  • Implement purge policies for obsolete observations to maintain performance.
  • Use descriptive OBSERVATION_TYPE values to streamline reporting.
In summary, PO_VENDOR_CONTACTS_OBS is a specialized table that augments Oracle EBS's vendor management capabilities by providing a structured repository for auxiliary contact information. Its design supports both operational and compliance needs, making it indispensable for organizations with complex supplier ecosystems.
