 ## Description
 
-This module allows grouping by product category in the stock valuation layer reports.
+This module allows grouping by product category at different hierarchy levels in the stock valuation layer reports.
 
 ### Problem
 
 By default, the `categ_id` field in `stock.valuation.layer` is a related field without storage (`store=False`). This means it cannot be used for grouping in reports and pivot views, even though it can be used for filtering and searching.
 
+Additionally, when dealing with hierarchical category structures (e.g., Food > Dairy > Cheese > Cheddar), it's often useful to group by different levels of the hierarchy.
+
 ### Solution
 
-This module makes the `categ_id` field stored (`store=True`) and indexed, which enables:
+This module makes the `categ_id` field stored (`store=True`) and indexed, and adds computed fields for each category hierarchy level (up to 4 levels), enabling:
-- Grouping by product category in list views
+- Grouping by product category (full path) in list, pivot, and graph views
-- Grouping by product category in pivot views
+- Grouping by category level 1 (top-level category)
-- Grouping by product category in graph views
+- Grouping by category level 2 (second-level category)
+- Grouping by category level 3 (third-level category)
+- Grouping by category level 4 (fourth-level category)
 - Better performance when filtering by category
 
 ## Installation
 
 1. Install the module from the Apps menu
-2. The field will be automatically populated for existing records
+2. The fields will be automatically populated for existing records
 
 ## Usage
 
 After installation:
 1. Go to Inventory > Reporting > Inventory Valuation
 2. Switch to Pivot or Graph view
-3. Click on "Measures" or group options
+3. Click on "Group By" options
-4. You will now see "Product Category" available for grouping
+4. You will now see multiple category grouping options:
+   - **Product Category**: Groups by the full category (leaf node)
+   - **Category Level 1**: Groups by top-level category
+   - **Category Level 2**: Groups by second-level category
+   - **Category Level 3**: Groups by third-level category
+   - **Category Level 4**: Groups by fourth-level category
+
+### Example
+
+If you have a category structure like:
+- Food (Level 1)
+  - Dairy (Level 2)
+    - Cheese (Level 3)
+      - Cheddar (Level 4)
+
+You can now group your inventory valuation by "Food" (Level 1), "Dairy" (Level 2), "Cheese" (Level 3), or "Cheddar" (Level 4) as needed.
 
 ## Technical Details
 
-The module extends `stock.valuation.layer` model and modifies the `categ_id` field to:
+The module extends `stock.valuation.layer` model and:
-- `store=True`: Store the value in the database
+- Modifies the `categ_id` field to: `store=True` and `index=True`
-- `index=True`: Add database index for better performance
+- Adds computed stored fields: `categ_level_1_id`, `categ_level_2_id`, `categ_level_3_id`, `categ_level_4_id`
+- Uses the `parent_path` field from `product.category` to determine hierarchy levels
 
-The field remains a related field, so it will automatically update when the product category changes.
+All fields are indexed for better performance and are automatically updated when product categories change.
