Select the Enterprise, property, revenue center, or zone,
click Configuration, and then click Menu Item Maintenance.
Click Search to show all menu items,
and then double-click a menu item master record.
Click the Definition Records tab
in the lower area of the screen.
In the Tare Weight field, enter
the weight of the empty package for an item that is sold by weight
(for example, the weight of the salad container at a salad bar, where
salad is sold by weight).
The Tare Weight should not be more
accurate than your scale can measure so that the application does
not round. For kilograms this is to the thousandth 0.000, for pounds
the hundredth 0.00, and for ounces the tenth 0.0.
Click Save.
Select the Enterprise, property, revenue center, or zone,
click Setup, and then click Control
Parameters.
Click the Options tab, and then
select 13 - Convert Weight to System Unit of Measure.
You must set this option in the United States to comply with
the Department of Agriculture Weights and Measure requirements. Setting
this option allows the POS client to convert the item weight to the
property’s UOM if the UOM received from a scale does not correspond
to the UOM set from the Property Parameters module.
