Hi,

When you do an inventory adjustment in Odoo, it changes stock levels but doesn't always affect the Profit & Loss report directly.

For P&L impact, the inventory adjustment must create a journal entry that posts a gain or loss.

This only happens if the product is set to "Automated Inventory Valuation" and real-time accounting.

If your product uses "Manual Inventory Valuation", Odoo won't post any accounting entry - so P&L stays the same.

You also need to make sure an "Inventory Loss Account" is properly configured on the product category.

If stock is decreased (e.g., -10 pcs), Odoo should post a cost to the Inventory Loss expense account, which appears on the P&L.

If none of these settings are correct, your inventory adjustment will only update stock levels, not financial reports.

To fix it, check the product's costing and valuation method, and ensure the correct accounts are set.

Hope it helps.
