+# MRP Components Report
+
+## Overview
+This custom Odoo 19 module adds a new "Components Required" report under the **Manufacturing > Reporting** menu. It allows users to view a consolidated list of components needed for Manufacturing Orders on a specific date (or within a selected date range).
+
+## Key Features
+- **Wizard Entry Point**: Allows users to filter required components by a custom date range.
+- **Reporting Views**: Provides robust List and Pivot views for analyzing component demand data.
+- **Multi-Level Grouping**: Components are pre-grouped by **Work Center** and then by **Parent Product** for clear visibility into production station needs.
+- **Excel Export**: Native Odoo list views support immediate export to `.xlsx`.
+- **Custom PDF Generation**: Includes a dedicated "Print PDF" action within the wizard for a neatly formatted printable report.
+
+## Technical Details
+This module utilizes a PostgreSQL `VIEW` (`mrp.components.report`) to performantly aggregate data from `mrp_production` (Manufacturing Orders) and `stock_move` (Component requirements). Work Center mapping is derived from standard Odoo routing and workorder relationships, gracefully falling back to the Manufacturing Order's primary Work Center if specific operations are undefined.
