We have the same problem, because our stock turnover is very low a days till reorder does not work for us as in some cases the stock turnover is so low the time in meaningless. We need the system to show out of stock when the stock level is below a set number.
It also will not work for us to have this setting on a different screen - the whole reason we installed ATUM was to get our stock level threshold and current stock into one place together.
Is there any solution for this? Can my developers modify the system?
