Expand/Collapse item  Overview

The use of negative quantities in standard bills is normally not advisable because they tend to distort cost calculations and may introduce errors when forecasting future requirements.

The Bill of Materials module, however, allows you to control the use of negative quantities in bills. Negative bill quantities are typically used to accommodate bills with options. A common method of defining bill options is to first create a base bill that represents the standard configuration and then create an option bill by defining those components that will be added to (positive quantity) or deleted from (negative quantity) the base bill. This type of structure defines an add/delete bill.
