I have an item that is configured as MTO-Buy. When I create and confirm an SO, a Draft PO is created - so far, so good. But when I reset the SO, change the quantity and confirm again, the following happens:

i) the PO is still in draft: the new quantity is added to the old one (example: SO 100 pieces - PO Draft 100 pieces - SO reset and changed to 80 pieces - PO Draft 180 pieces!).

ii) the PO has already been confirmed: New PO over 80 pieces is created.

In both cases, 100 pieces are ordered too much (if the clerk is not careful). An error message will certainly appear on the PO, but this is easy to overlook.

I simply cannot believe that this is correct system behavior. Have we misconfigured something or overlooked something else?
