Stock Inventory Adjustment Security

Overview

This module adds granular security controls for inventory adjustments in Odoo. It allows you to separate the ability to count inventory from the ability to apply adjustments.

Features

• New Security Group: "Inventory: Manual Adjustments"
• Separation of Duties:
  • Regular inventory users can view stock and enter counted quantities
  • Only privileged users can apply the adjustments to modify actual stock levels
• No Impact on Automatic Operations: Stock moves from pickings, manufacturing orders, and other automatic operations work normally

Use Case

Perfect for organizations that want to:

• Allow warehouse staff to participate in inventory counts
• Restrict who can actually modify stock levels
• Maintain audit trails by limiting adjustment privileges
• Implement proper inventory control procedures

How It Works

Technical Implementation

The module overrides the write() method on stock.quant to check:

1. If the operation is in "inventory mode" (manual adjustment context)
2. If the quantity field is being modified
3. If the user has the required security group

The check uses Odoo's built-in _is_inventory_mode() method which returns True only when:

• The inventory_mode context flag is set (manual adjustments)
• The user has the stock.group_stock_user group

User Experience

Regular Inventory User:

• Can navigate to Inventory > Inventory Adjustments
• Can view current stock quantities
• Can enter counted quantities in the inventory_quantity field
• Cannot click "Apply" to commit the changes
• Receives clear error message when attempting to apply

Privileged User (with Manual Adjustments group):

• Can do everything a regular user can do
• Can click "Apply" to commit inventory adjustments
• Can modify actual stock quantities

Configuration

1. Install the module
2. Go to Settings > Users & Companies > Users
3. Edit a user who should be able to apply inventory adjustments
4. Add them to the "Inventory: Manual Adjustments" group

Testing

The module includes comprehensive test coverage:

# Run all tests
odoo-bin -d your_database -i stock_inventory_adjustment_security --test-enable --stop-after-init

# Run specific test class
odoo-bin -d your_database --test-tags stock_inventory_adjustment_security

Test Cases

• ✅ Regular users can set inventory_quantity (count)
• ✅ Regular users cannot apply adjustments
• ✅ Privileged users can apply adjustments
• ✅ Automatic operations (pickings, etc.) are not affected
• ✅ Inventory mode detection works correctly
• ✅ Multiple quant adjustments work correctly
• ✅ Non-inventory mode writes are not restricted

Compatibility

• Odoo 18.0
• Depends on: stock
