Negative picking, also known as negative picking, refers to the fact that there may be a slightly higher quantity than actually required within a staging unit. Let's assume that the quantity in stock at the picking station is higher than the quantity needed for the shipping unit to be packed. For organizational and practical reasons, it would make little sense to intervene and repackage there. Instead, the picker walks over and turns the staging unit into a shipping unit - the quantity that is then actually not needed is then placed on an empty pallet that is present at the staging location.
Thus, by picking the residual unit, one avoids cumbersome handling, which would cause time and costs.
