It is the average see the test scenario: http://hg.tryton.org/modules/product_cost_fifo/file/3f9793486d52/tests/scenario_product_cost_fifo.rst#l122 I did some more tests with incoming and outgoing moves: cost price method = fifo Supplier ShipmentAccount move Quantity Price Debit Credit - Product_15.00 5.00 25.0025.00 Product_15.00 10.00 50.0050.00 Customer ShipmentAccount move Quantity Price Debit Credit - Product_17.00 fifo 45.0045.00 ^ | +- 5*5+2*10 - OK stock moves - ok account moves - ok but on Product form you can see: Cost Price 3.75 - this is neither average price (7.5 in this case) nor the one of fifo prices (5 or 10) How this value is calculated ? It is the average but of course it depends on the initial values. By the way There is also a functional field cost_value in stock module which is also not working with fifo cost pricing method. You can see cost_value on Inventory Stock-Locations, dbl click on location an there is a report Products by locations. There is: Product TemplateQuantity Cost Value - Product_1 3.0011.25 while there should be: Product TemplateQuantity Cost Value - Product_1 3.0030.00 I see that function stock.location.get_cost_value() does simple calculation product.cost_price * location.quantity, while it could use function product.template.get_fifo_move() from module product_cost_fifo. This will be too slow so by using the average normally we get the right value. -- Cédric Krier - B2CK SPRL Email/Jabber: cedric.kr...@b2ck.com Tel: +32 472 54 46 59 Website: http://www.b2ck.com/ pgpp_lR0uWrii.pgp Description: PGP signature

As I understand cost_price is a calculation of average prices of what is not consumed yet (it is ok for me) I do the following tests: Test 1) Supplier Shipment Account move Line No Quantity Price Debit Credit -- 1 Product_15.00 5.00 25.0025.00 2 Product_15.00 10.00 50.0050.00 Customer Shipment Account move Line No Quantity Price Debit Credit -- 1 Product_17.00 fifo 45.0045.00 Cost Price 3.75 WRONG PRICE -- There is probably a bug when same product is on many lines. Please report it and even better with a test scenario. -- Cédric Krier - B2CK SPRL Email/Jabber: cedric.kr...@b2ck.com Tel: +32 472 54 46 59 Website: http://www.b2ck.com/ pgpGPDfLv6GlJ.pgp Description: PGP signature

2014-07-04 14:46 GMT+02:00 Michal michal.s...@gmail.com: Accordingly there is a need to have different account_stock value for the same product in different warehouses. do you mean stock value increases when you move a product from location 1 to location 2 and decreases if you move it back ? Are you sure we talk about the save cost ?

Cost_price_method could be fixed, average and fifo. Cost_price is a part of a product.template model. First consequence I have noticed is that calculating amount in stock move lines we have always one price for a product in a whole company. Is there a possibility to have different cost prices in different warehouses ? For example I can have 2 warehouses in 2 departments of my company, each of them in different city. If I have the same product in both of them and I make a move from supplier or production to one of them the cost_price is changing in both of them (cost_price_method = average). Accordingly there is a need to have different account_stock value for the same product in different warehouses. This is not supported by Tryton for now. But it could be an improvement to add a extra computation of cost price per warehouse. Second consequence is that when I make 2 moves from supplier or production to warehouse in different prices (cost_price_method = fifo) cost_price on product form is not displayed properly. Why is there any value ? Could it be a list of a current fifo_quantities like in product.template.get_fifo_move() instead of showing a value. I don't understand. -- Cédric Krier - B2CK SPRL Email/Jabber: cedric.kr...@b2ck.com Tel: +32 472 54 46 59 Website: http://www.b2ck.com/ pgp4psmLJy63M.pgp Description: PGP signature
