In the purchase order, when having to un-receive items, it would be nice if we are able to choose which tier we want to un-receive. We are using FIFO, and it is creating an average cost tier. This can create a material cost nightmare. Right now it does not give us the option to chose which tier we want to "un-receive". It appears that when we go into the purchase order, and un-receive, that we are doing it at the same cost, however, it is not. Its using an average cost. It would be nice if it gave us the option to pick the cost that went in wrong.
