MSC Pegging Hierarchy - Case Study & Technical Analysis
Executive Summary
The MSC Pegging Hierarchy report provides a deep-dive view into the complex supply chain relationships established by ASCP. It traces the lineage from a top-level demand (like a Sales Order) down through all levels of the Bill of Materials and distribution network to the ultimate supply source.
Business Challenge
In a multi-org, multi-level supply chain, it’s hard to know “why” a supply order exists.
- Traceability: “This Purchase Order is for a raw material. Which specific customer order is it supporting?”
- Impact Analysis: “If this shipment from the supplier is delayed, which finished goods in which distribution centers will be affected?”
- Allocation: “We have limited supply. Which orders should we prioritize?”
Solution
The MSC Pegging Hierarchy report visualizes the full pegging tree.
Key Features:
- End-to-End Trace: Links Independent Demand (SO) -> Dependent Demand (WIP) -> Supply (PO/Work Order).
- Multi-Org: Can trace pegging across different organizations (e.g., Factory -> Distribution Center).
- Details: Shows dates, quantities, and order numbers at each level of the hierarchy.
Technical Architecture
The report uses the MSC_FULL_PEGGING table, which stores the parent-child links generated by the planning engine.
Key Tables and Views
MSC_FULL_PEGGING: The core table storing the graph of transaction links.MSC_DEMANDS: Details of the demand side.MSC_SUPPLIES: Details of the supply side.MSC_SYSTEM_ITEMS: Item attributes.
Core Logic
- Root Selection: Starts with a specific demand or supply transaction.
- Recursive Traversal: Uses a
CONNECT BYquery (or recursive CTE) to traverse theMSC_FULL_PEGGINGtable up or down the tree. - Enrichment: Joins to the supply/demand tables to get human-readable details.
Business Impact
- Customer Service: Enables accurate “Available to Promise” (ATP) checks and proactive notification of delays.
- Inventory Management: Helps identify “orphan” supply that can be cancelled.
- Supply Chain Visibility: Provides a clear map of material flow across the enterprise.
Oracle E-Business Suite Reporting Library
We provide an open source Oracle EBS SQLs as a part of operational and project implementation support toolkits for rapid Excel reports generation.
Blitz Report™ is based on Oracle EBS forms technology, and hence requires minimal training. There are no data or performance limitations since the output files are created directly from the database without going through intermediate file formats such as XML.
Blitz Report can be used as BI Publisher and Oracle Discoverer replacement tool. Standard Oracle BI Publisher and Discoverer reports can also be imported into Blitz Report for immediate output to Excel. Typically, reports can be created and version tracked within hours instead of days. The concurrent request output automatically opens upon completion without the need for re-formatting.
The Filters, Columns, Rows and Values fields are used to create and deliver the data in pivot table format with full drill down to details.

The Excel template upload functionality in Blitz Report allows users to create their own layouts by uploading an Excel template with additional sheets and charts, automatically refreshed when the report runs again. This allows to create custom dashboards and more advanced visualizations of report data.

You can download and use Blitz Report free of charge for your first 30 reports.
The installation and implementation process usually takes less than 1 hour; you can refer to our installation and user guides for specific details.
If you would like to optimize your Oracle EBS implementation and or operational reporting you can visit www.enginatics.com to review great ideas and example usage in blog. Or why not try for yourself in our demo environment.
