Storage unit (SU) management in Warehouse Management (WM) enables you to optimize warehouse capacity and control material flow by utilizing storage units within the warehouse.

A storage unit is a logical grouping of one or several amounts of material such as a pallet or a container that can be managed within a warehouse as a unit that belongs together. Storage units can be either homogeneous (containing one material item only) or mixed (containing two or more material items).

All storage units, whether the materials are stored on standard pallets, wire baskets or other containers, are assigned an identifier a number which is maintained in the system as the storage unit number. Therefore, it is possible at any given time to know where each storage unit is located in the warehouse complex, the amount of material contained in it, and which operations have been processed or planned for it.
