Hi,

In Odoo 19, manual inventory adjustments no longer automatically create journal entries if the product category valuation is set to “Perpetual (At invoicing),” unlike Odoo 18 where such entries were sometimes generated. As a result, opening stock valuations from manual adjustments do not appear in ledgers or accounting reports. To restore the automatic flow, you can either change the product category valuation to “Perpetual (Automated)” so that inventory adjustments generate accounting entries, use the dedicated “Opening Inventory” feature to import stock balances, or create the journal entries manually for opening stock. This change ensures that stock value is only recorded when stock moves are linked to invoices, maintaining accurate accounting under the “At invoicing” method.
