A purchase order was created, was confirmed, goods related to it was received.
At this stage, one of the products was incorrectly entered in the purchase order. Lets say, goods recieved is item B( we actually want item B), good in purchase order was purchase A.
The purchase order seems can not be canceled since it says
Unable to cancel this purchase order.
First cancel all receptions related to this purchase order.
And there is no way to " cancel all receptions", seems once goods received, there is no undo.
How could this be handled, so that in openerp refacts the fact that item B was recieved, item A wasn't.
