I should really read more carefully the code. 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 Shipment Account move > Quantity Price Debit Credit > --------------------------------------------------------- > Product_1 5.00 5.00 25.00 25.00 > Product_1 5.00 10.00 50.00 50.00 > > Customer Shipment Account move > Quantity Price Debit Credit > --------------------------------------------------------- > Product_1 7.00 fifo 45.00 45.00 > ^ > | > +----- 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 ?

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/
