Some Oracle EBS SQL reports in this library require functions from the utility package xxen_util. Install it before running the SQL directly against your Oracle EBS database.

The Blitz Report Parameter Custom LOV Duplication Validation is a maintenance and optimization tool for Oracle E-Business Suite. It identifies opportunities to refactor and streamline report definitions by detecting redundant custom List of Values (LOV) queries. The goal is to promote the use of shared LOVs, reducing maintenance overhead and ensuring consistency across the reporting landscape.
In the lifecycle of report development, it is common for developers to define "Custom" LOVs directly within a report parameter using a specific SQL query. Over time, the same SQL logic (e.g., "Select all active Cost Centers") might be pasted into dozens of different reports.
- Maintenance Nightmare: If the business logic for "Active Cost Centers" changes, developers must manually locate and update every single report that uses that specific SQL snippet.
- Inconsistency: If one report is updated and another is missed, users will see different lists of values for the same business concept.
- Redundant Storage: Storing the same SQL text multiple times bloats the metadata repository.
This report scans the Blitz Report metadata repository to identify parameters that use identical SQL queries for their LOVs but are not linked to a shared LOV definition.
- Identification: It lists all parameters where the LOV query text is duplicated across multiple reports or parameters.
- Recommendation: The output serves as a "to-do" list for developers to create a single, shared LOV (e.g., "GL Active Cost Centers") and link all identified parameters to it.
- Standardization: Encourages a "define once, use many" architecture.
The report analyzes the xxen_report_parameters_v view. It groups parameters by their lov_query (SQL text) and filters for those where the count is greater than 1, indicating duplication.
xxen_report_parameters_v: The source of parameter definitions and their associated LOV SQL text.
- Category: Allows users to filter the validation check by specific report categories (e.g., "Finance", "Supply Chain") to prioritize cleanup efforts.
The report runs quickly as it performs a text-based aggregation on the metadata tables.
Q: Why should I use shared LOVs instead of custom ones? A: Shared LOVs are central objects. If you need to change the logic (e.g., exclude a specific Org ID), you change it in one place, and all 50 reports using that LOV are instantly updated.
Q: Does this report automatically fix the duplicates? A: No, it is a diagnostic tool. It identifies the duplicates so a developer can decide which ones should be converted to a shared LOV.
