What is the "Default discountable on vendor bills" Option When Creating a Class?

When creating a new class, you may notice a checkbox labeled "Default discountable on vendor bills" in the Inventory profile section. This article explains what this setting does and when it applies.

What does this setting do?

The Default discountable on vendor bills option is related to the Accounts Payable (AP) module. When checked, it marks purchase order (PO) lines associated with this class as eligible to receive a discount on vendor bills. If unchecked, those lines will not be considered discountable.

Who does this apply to?

This setting only has an effect if your organization is using the AP module. If you are not using the AP system, this checkbox has no impact on your class configuration and can be safely ignored.

Why doesn't this option appear when editing an existing class?

The Default discountable on vendor bills checkbox is only shown during the initial creation of a new class. It is not displayed on the class edit form. This is expected behavior, the setting is applied at the time of class creation as a default for new records associated with that class.
