Stock Valuation Layer Category Groupby

Description

This module allows grouping by product category 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.

Solution

This module makes the categ_id field stored (store=True) and indexed, which enables:

• Grouping by product category in list views
• Grouping by product category in pivot views
• Grouping by product category in graph views
• 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

Usage

After installation:

1. Go to Inventory > Reporting > Inventory Valuation
2. Switch to Pivot or Graph view
3. Click on "Measures" or group options
4. You will now see "Product Category" available for grouping

Technical Details

The module extends stock.valuation.layer model and modifies the categ_id field to:

• store=True: Store the value in the database
• index=True: Add database index for better performance

The field remains a related field, so it will automatically update when the product category changes.
