Comment 2 for bug 388145

To get your expected result for step 1 and step 2, you can easily configure, putting the right accounts on the product (or category).

Step 4 is clearly not possible (how can Open ERP know the price you purchased the delivered products ? the only possibility is to use only MTO operations or tracking number on every move, which is nor acceptable) does it uses the standard or average cost ?

From which country are you ?
