Hi Edward

By definition, a residual value can only exist when the quantity on hand is zero, so your question #1 is impossible to answer.

If an item has multiple lots which sum up to zero, you will need to collapse the lots. But that is a totally separate issue from residual values. The easiest way to collapse multiple lots is to reassign the item's account set to one that is using Moving Average as the costing type, save it, and then change it back to the original account set.
