Search Results requisition




The APPS.POA_REQ_000_MV table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a materialized view associated with the Procurement (PO) module, specifically designed to support reporting and analytical requirements for purchase requisitions. Materialized views in Oracle EBS are precomputed result sets stored as database objects to enhance query performance, particularly for complex aggregations or frequently accessed data. This table is part of Oracle's strategic approach to optimize reporting performance while reducing the load on transactional tables.

Purpose and Functional Context

The APPS.POA_REQ_000_MV materialized view aggregates data from underlying transactional tables related to purchase requisitions, such as PO_REQUISITION_HEADERS, PO_REQUISITION_LINES, and other supporting tables. Its primary purpose is to streamline reporting for procurement analytics, requisition tracking, and approval workflows. By pre-joining and summarizing data, it eliminates the need for resource-intensive queries on transactional tables during real-time reporting.

Key Data Attributes

The view typically includes critical requisition attributes such as:

  • Requisition Header Data: Requisition ID, creation date, requester, status, and approval details.
  • Line-Level Details: Item descriptions, quantities, unit prices, and accounting distributions.
  • Supplier and Sourcing Information: Preferred suppliers, sourcing rules, and negotiation details.
  • Workflow and Approval Metrics: Approval hierarchies, pending actions, and historical approval timelines.

Technical Implementation

As a materialized view, APPS.POA_REQ_000_MV is refreshed periodically (e.g., daily or via incremental refreshes) to synchronize with source tables. The refresh mechanism can be configured using Oracle's DBMS_MVIEW package or through Oracle EBS concurrent programs. In EBS 12.2.2, it may leverage Oracle Database's advanced features like partitioning or query rewrite for further optimization.

Integration with Oracle EBS Modules

The view integrates with:

  • Inventory (INV): Links requisitioned items to inventory stock levels.
  • General Ledger (GL): Provides accounting distributions for budgetary control.
  • Oracle Workflow: Tracks requisition approval processes.

Customization and Extensions

Organizations often extend this view by adding custom columns or creating derivative materialized views to meet specific reporting needs. However, direct modifications to Oracle-delivered objects are discouraged; instead, customizations should be implemented through extensions or ancillary tables.

Performance Considerations

In EBS 12.2.2, the view benefits from Oracle's In-Memory Column Store (if licensed) for faster analytics. Proper indexing on columns frequently used in WHERE clauses (e.g., requisition_header_id) is recommended.

Deprecation and Alternatives

In later versions of Oracle EBS or Fusion Applications, this materialized view may be replaced by Oracle Transactional Business Intelligence (OTBI) or Fusion Analytics Warehouse. However, in 12.1.1 and 12.2.2, it remains a key component for procurement reporting.

Note: The exact schema and columns may vary based on patch levels and customizations. Always verify the structure via DESC APPS.POA_REQ_000_MV in your environment.
