# Master Data Quality Manager

## Overview

The Master Data Quality Manager provides supply chain master data quality monitoring, validation, and improvement capabilities. It ensures data accuracy across item, supplier, location, and BOM master data to support reliable supply chain operations and analytics.

## Capabilities

- **Item Master Data Validation**: Product data completeness and accuracy
- **Supplier Master Data Cleansing**: Vendor data quality improvement
- **Location/Plant Data Verification**: Facility data accuracy
- **BOM Accuracy Checking**: Bill of materials validation
- **Lead Time Validation**: Lead time data accuracy assessment
- **Data Completeness Scoring**: Missing data identification
- **Duplicate Detection**: Redundant record identification
- **Data Quality Trending**: Quality metric tracking over time
