Multiple warehouses is an option that allows to insert the same item in multiple warehouses while centralizing the inventory. This allows for changes in physical location of the warehouse but makes it possible to control the entire inventory from one workstation.
This option can be found under "Program management".
Once this option is active, a new field will appear in the items list which will show the physical storage location of each item.
Additionally, the "Tables" menu of the program will now contain
an additional item "Warehouse location".
