Hi,

This issue occurs because Odoo cannot find a valid replenishment or transfer rule for one or more products when confirming a sale order. In multi-warehouse setups or when using “In Transit” routes, Odoo needs a complete route configuration that defines how stock moves between locations (for example, from Warehouse A → Transit → Warehouse B → Customer). If any step in that route is missing a rule, the system raises the “No replenishment rule found” error.

To fix it, you need to verify that the product’s routes are correctly assigned under the Inventory tab, ensuring the proper route (such as Buy, Make to Order, or Inter-Warehouse Transfer) is selected. Next, check the route rules under Inventory → Configuration → Routes — each route should include push or pull rules linking all required locations, with correct operation types and source/destination locations.

Also, review your warehouse configuration to confirm that input, stock, output, and transit locations are properly defined and connected to the routes. If you are unsure where the error occurs, temporarily apply a standard route like “Deliver from WH/Stock” to see if it resolves the issue — this helps identify problems in custom routes.

In short, the error happens because the route configuration for transferring products is incomplete. Once every location and rule is properly defined in your inter-warehouse or delivery route, Odoo will be able to confirm the sales order without any issues.

Hope it helps
