Im using Odoo 9, Im trying to implement perpetual inventory valuation, using the purchase, inventory, sales and accounting modules

but basically the problem is that when the goods are received in the warehouse after invoicing, the proper journal entry is not made to reflect the value of the goods in the Inventory (current assets) account, the whole amount just sits there in cost of good sold. (expense)

The same thing happens when i make a sale, the cost of the good sold is not discounted from the inventory. 

I dont know if Im skipping a step or I need to make the entre manually

Hope you can help
