Managing locations is one of warehouse features and includes both fixed and free locations. Fixed locations are associated with a specific item and are set aside to it even though the balanced within it is 0.
Free location is associated instead with a specific item just until there’s a balance for it. Free locations enable to optimize spaces in warehouses and give the possibility to associate more items to a single location.
It’s also possible to choose for each item a specific location, according to its both morphological and management characteristics, in which the system suggests when entering or put into production.
