## Description

Delete a single item parameter.
            
Some items can be taxed differently depending on the properties of that item, such as the item grade or by a particular measurement of that item. In AvaTax, these tax-affecting properties are called "parameters".
            
A parameter added to an item will be used by default in tax calculation but will not show on the transaction line referencing the item .
            
A parameter specified on a transaction line will override an item parameter if they share the same parameter name.
