Blitz Report LOV Comparison between environments - Case Study & Technical Analysis
Executive Summary
Blitz Report LOV Comparison between environments is a technical validation tool for List of Values (LOV) definitions. It compares the SQL queries behind the parameter dropdowns between two environments. This ensures that the parameters available to users (e.g., the list of “Cost Centers” or “Suppliers”) behave identically after a migration.
Business Challenge
- Broken Parameters: A report works in Dev, but in Prod, the “Department” dropdown is empty because the underlying LOV SQL references a table that doesn’t exist or has different permissions.
- Inconsistent Data: The LOV in Dev filters out inactive suppliers, but the Prod version doesn’t, leading to users selecting invalid options.
Solution
This report compares the XXEN_REPORT_PARAMETER_LOVS_V view across a database link.
- SQL Comparison: It compares the
LOV_QUERYtext. - CLOB Handling: Like the report comparison, it requires a special view on the remote side to handle the potentially long SQL text of the LOV definition.
Technical Architecture
Key Tables
XXEN_REPORT_PARAMETER_LOVS_V: The definition of the LOVs.- Remote View (
XXEN_REPORT_PARAMETER_LOVS_V_): The helper view for DB Link access.
Logic
- Match LOVs: Matches based on LOV Name.
- Compare SQL: Checks if the query text differs.
Parameters
- Remote Database: The target environment.
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.
