The ASF_USER_PREFERENCE table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical data structure within the Application Object Library (AOL) module. It stores user-specific preferences and settings that customize the behavior and appearance of Oracle EBS applications for individual users. This table plays a pivotal role in personalizing the user experience by retaining configurations such as default forms, report formats, display options, and other session-based preferences. Below is a detailed analysis of its structure, functionality, and significance in Oracle EBS implementations.

Table Structure and Key Columns

The ASF_USER_PREFERENCE table consists of several columns that define user preferences at a granular level. Key columns include:
  • USER_PREFERENCE_ID: A unique identifier for each preference record, typically a sequence-generated primary key.
  • USER_ID: References FND_USER.USER_ID, linking preferences to specific EBS users.
  • PREFERENCE_NAME: A descriptive name for the preference (e.g., "DEFAULT_FORMAT" or "TIMEZONE_SETTING").
  • PREFERENCE_VALUE: The actual value assigned to the preference (e.g., "PDF" for report format).
  • APPLICATION_ID: Associates the preference with a specific EBS application module (e.g., GL, AP).
  • CREATION_DATE and LAST_UPDATE_DATE: Audit columns tracking record creation and modification timestamps.

Functional Role in Oracle EBS

The table enables the following functionalities:
  1. Personalization: Users can set default behaviors (e.g., default homepages, favorite menus) that persist across sessions.
  2. Localization: Stores locale-specific settings like date formats, numeric separators, or language preferences.
  3. Workflow Customization: Retains user-selected options for approval workflows or notification methods.
  4. Integration: Preferences may influence integration with external systems (e.g., default file export paths).

Technical Considerations

  • Performance: Indexes on USER_ID and APPLICATION_ID optimize preference retrieval during login.
  • Security: Data is protected via Oracle EBS’s standard VPD (Virtual Private Database) policies.
  • APIs:
    • FND_PROFILE package is often used to interact with preferences programmatically.
    • Direct DML operations are discouraged; preference updates should use Oracle-provided APIs.

Version-Specific Notes

Differences between EBS 12.1.1 and 12.2.2 are minimal for this table, but 12.2.2 may include:
  • Additional preference types for new features like Oracle Fusion Middleware integration.
  • Enhanced encryption for sensitive preference values (e.g., saved passwords).

Customization and Extensions

Implementers often extend the table’s usage by:
  • Adding custom preference types via FND_PROFILE.OPTIONS.
  • Leveraging the table to store application-specific settings beyond Oracle’s out-of-box functionality.

Conclusion

The ASF_USER_PREFERENCE table is foundational to Oracle EBS’s user-centric design, ensuring consistency and efficiency in enterprise operations. Its structured yet flexible architecture supports both standard and customized implementations, making it indispensable for administrators and developers alike. Proper management of this table—through APIs and adherence to Oracle’s best practices—ensures optimal system performance and user satisfaction.
