The AS_ACC_USR_RANKS_ALL table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Oracle Advanced Supply Chain Planning (ASCP) module. This table stores user ranking information related to access control for planning responsibilities, ensuring that users have appropriate permissions to view or modify planning data based on their assigned roles. Below is a detailed analysis of its purpose, structure, key columns, and functional significance in Oracle EBS.

Purpose and Context

The AS_ACC_USR_RANKS_ALL table is part of Oracle ASCP's security framework, which governs user access to planning data. It enables hierarchical access control by associating users with specific ranks or privilege levels. This ensures that users can only interact with data pertinent to their organizational role, such as planners, managers, or administrators. The table is particularly relevant in multi-organization environments where data segregation is mandatory.

Table Structure and Key Columns

The table's structure includes columns that define user-rank relationships, organizational context, and access privileges. Key columns include:
  • USER_ID: References FND_USER.USER_ID, linking to the Oracle EBS user account.
  • RANK_ID: Identifies the rank or privilege level assigned to the user (e.g., 1 for high-level access).
  • ORGANIZATION_ID: Specifies the inventory organization (from ORG_ORGANIZATION_DEFINITIONS) to which the rank applies.
  • CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE: Audit columns tracking record creation/modification.
  • LAST_UPDATE_LOGIN: Session identifier for the last update.

Functional Significance

  1. Access Control: The table enforces role-based access to planning data. For example, a regional planner may have a lower rank than a global planner, restricting their visibility to specific organizations.
  2. Multi-Org Support: The _ALL suffix indicates the table stores data across operating units, aligning with Oracle EBS's multi-org architecture.
  3. Integration with ASCP: Ranks defined in this table influence data visibility in ASCP workflows, such as demand planning, supply planning, and inventory optimization.
  4. Security Compliance: By segregating data access, the table helps meet regulatory requirements (e.g., SOX, GDPR) for data confidentiality.

Technical Considerations

  • Indexes: Typically indexed on USER_ID, RANK_ID, and ORGANIZATION_ID for performance optimization.
  • Dependencies: Relies on FND_USER for user details and ORG_ORGANIZATION_DEFINITIONS for org validation.
  • APIs Oracle provides PL/SQL APIs (e.g., in AS_ACCESS_CONTROL_PKG) to manage ranks programmatically.

Customization and Extensions

While Oracle discourages direct DML on this table, customizations can be implemented via:
  • Personalization: Using Oracle's Access Control Manager to assign ranks via GUI.
  • API Calls: Leveraging public APIs to automate rank assignments during user provisioning.

Conclusion

The AS_ACC_USR_RANKS_ALL table is a cornerstone of Oracle ASCP's security model in EBS 12.1.1 and 12.2.2. Its design ensures granular access control, supports multi-org deployments, and integrates seamlessly with planning workflows. Understanding its schema and functionality is essential for administrators configuring ASCP security or troubleshooting access issues.
