Quantity in stock unit calculated from the ordered quantity in order unit.
If the entered quantity is not a multiple of the order unit, a warning message is displayed. By default the minimum purchase quantity or the quantity of considered requirements is suggested. Under no circumstances the quantity entered is lower than these quantities.
You can modify this quantity if the order unit is a product packing unit, whose coefficient can be modified (see Packing unit table on the Units section of the Product record) but cannot be used with the other units (product purchase unit, supplier purchase unit, supplier packing unit, stock unit).
If you modify the quantity in stock unit, the factor expressed between the order unit and the purchase unit is adjusted.
