OE 16

I buy a product P from by supplier and get only invoiced for ordered qty

Product P with AVCO as costing method

I buy 10 P at 100€/piece, I receive 10 P, the cost of P is set to 100 €, which is fine

I buy 10 P at 200 €/piece,I receive 10 P, the cost of P is set to 150 €, which is fine

I buy 10 P at 175 € /piece, I receive 12 P, the cost of P is set to 159,38 €, which is not correct

When I process the lastest move the computation that is made is

10*100+10*200+12*175=5100 / 32 = 159,30 €

5100 € is correct as the stock valuation but the cost price should be 10*100+10*200+10*175=4750 / 32 = 148,44 €

Any comment is more than welcomed
