[FIX] purchase_stock,stock_account: create only one SVL for price diff
When confirming a bill with a price diff, if the user received, returned and received again the products, some unexpected valuation layers will be generated To reproduce the issue: (Need account_accountant, sale_management) 1. Create a product category PC: - Costing Method: FIFO - Inventory Valuation: Automated 2. Create a product P - Type: Storable - Category: PC 3. Create and confirm a PO with - 3 x P at $50 4. Process the receipt R01 5. Create and process the return RT01 of R01 6. Create and process the return RT02 of RT01 7. Create and confirm a SO with - 1 X P 8. Process the delivery 9. Create the bill related to PO 10. Set the bill line unit price to $60 11. Confirm 12. Open the valuation of P Error: There are two lines for the price difference, there should be one line only. Moreover, the value is incorrect: 30 instead of 10 (i.e. we should generate the price diff layer for the quantities in stock only) When confirming the bill, we check if we have to generate some additional SVL (in case of price diff) https://github.com/odoo/odoo/blob/d3d41c7679f9068a7b986925b15d0d7670233bfc/addons/stock_account/models/account_move.py#L288-L305 But, we get all ingoing SVL and process them, we don't consider that the quantity of a SVL might actually be returned and should be ignored. This is the reason why a SVL is created for the first receipt. This also explains why the value is incorrect (we use the quantity of the SVL instead of its remaining quantity) OPW-3040171 X-original-commit: 18912b05239e6fc5dab26ec4c930f9080882d127 Part-of: odoo/odoo#107145
