I followed all the instruction given by odoo document section (https://www.odoo.com/documentation/user/13.0/inventory/routes/costing/landed_costs.html), but when I press the button to calculate the landed cost there is a message that says something like this (i translate it literally) "The selected delivery note does not contain any movement that impacts the landed costs. Landed costs are only possible for products configured with real-time valuation using the real cost price method. Make sure that this is the case, or that you have selected the appropriate delivery note."

All products and landed cost are configured with that valuation method, but I can't find where is the mistake.

Please help!!
