i've changed the decimal precision for the cost_price. i put it to 4. but, when I make a new purchase for a product, the calculation of the new cost_price is based on 2 decimals then it is displayed on 4 Decimals.
What can I do to adjust the problem?
An exple: having put the decimal precision "product price" and "account" to 4 and the method of calculating cost to "average price". I make simulation of a computing cost for Article X.
I start with qty in stock: 149 cost price = 340.8322
new acquisition: qty = 23 purchase price = 326.22
after receipt, result: qty = 172 cost = 338.8763
manual calculation I found: qty = 172 and cost = 338.8782 which is <> that gave OpenERP.
I round cost price to 2 and recalculate.I find the same value OpenERP: ((149 * 340.83 + 23 * 326.22) / (149 +23) = 338.8763 that's the pb
