Hi,

The error message "No rule has been found to replenish '(product name)' in 'Partner Locations/Customers'. Verify the route configuration on the product." typically occurs in Odoo when there's an issue with the route configuration for the product. This error indicates that there are no procurement rules defined to manage the replenishment of the product from one location to another.

Firstly navigate configuration-->Warehouse-->select the warehouse-->Routes , Then check the routes and rules thoroughly and make sure there is a rule for Partner Locations/Customers Location, is not there change or add the route and rule correspondingly, By following these steps and ensuring that the routes and rules are properly configured, you should be able to resolve the error related to replenishing the product between the specified locations in Odoo.

Hope it helps
