Where? Side Menu > Barrels > Rackhouse Inventory > Rackhouse Inventory.
Once a Warehouse has been setup in Warehouse Management Setup (Setup Wizard), and Warehouse Zones have been assigned to Barrels from the Barrel Warehouse, an overview of the Warehouse Inventory will be displayed graphically in Warehouse Inventory:
Here each row and tier in each zone can be examined to show current location of barrels in your warehouse. Zones will change color as barrels are assigned with Green denoting an empty row/tier, Yellow as partial and Orange as full.
Clicking on a specific row/tier inventory will pull up all barrels assigned to that location in the barrel rackhouse view.
See Warehouse Management Setup for more information on how to get your warehouses setup.
