MRP Exceptions - Case Study & Technical Analysis
Executive Summary
The MRP Exceptions report is the primary “to-do list” for material planners. It filters the massive amount of data generated by an MRP run into actionable alerts. Instead of reviewing every item, planners focus only on items where the plan is “broken” or requires intervention, such as late orders, potential shortages, or excess inventory.
Business Challenge
An MRP run might generate thousands of planned orders and recommendations. Planners cannot review them all. They need to know:
- Urgency: “Which orders are already late and need immediate expediting?”
- Efficiency: “Which orders can be cancelled because the demand went away?”
- Data Integrity: “Which items have missing lead times or invalid planning parameters?”
Solution
The MRP Exceptions report highlights these specific issues using standard exception messages.
Key Features:
- Action-Oriented: Groups items by exception type (e.g., “Orders to be cancelled,” “Orders with compression days”).
- Prioritization: Allows filtering by Planner Code, so each planner sees only their own items.
- Details: Provides the specific context (e.g., “Order 123 is late by 5 days”).
Technical Architecture
The report queries the exception messages generated during the planning process.
Key Tables and Views
MRP_EXCEPTION_DETAILS_V: The primary view containing the exception messages linked to specific items and plans.MTL_SYSTEM_ITEMS_VL: Provides item descriptions and planning attributes.MTL_PLANNERS: Used to filter exceptions by the responsible planner.
Core Logic
- Exception Generation: During the MRP run, the engine identifies conditions that violate planning rules (e.g., supply date > need date).
- Categorization: These conditions are flagged with specific Exception Types (e.g., Type 10 = “Orders to be cancelled”).
- Reporting: The report retrieves these records, joined with item and planner details for context.
Business Impact
- Productivity: Drastically reduces the time planners spend analyzing data, allowing them to focus on fixing problems.
- Responsiveness: Ensures that critical shortages (potential stockouts) are identified and addressed immediately.
- Cost Reduction: Helps identify excess inventory (orders to cancel) and avoid unnecessary expediting costs.
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.
