Inventory Settings can be managed by navigating to Settings via the dark blue bar across the top of your screen, then navigating about halfway down the left hand list of setting sub-modules. You must have enough permissions to see these options. If you cannot see them and need to use them, contact your administrator.
Administrators may permit user groups to see and adjust the inventory settings by enabling the following settings in the applicable user group:
Settings → Configuration
Configuration options as relate to the inventory module
Unique Product Codes:
Checking off ‘Product codes must be unique’ in Settings → Configuration / Inventory and purchase will enforce unique product codes. This is a recommended setting, particularly if inventory is to be updated via import.
Automatic Code/UPC code Generation:
To automatically generate codes or UPC codes use the checkboxes in the Settings → Configuration / Inventory and purchase. NOTE: imported items, via inventory import or invoice import will not generate codes.
