Changing Bills of Material 

Use

You use this method of changing bills of material when you just want to change a single BOM.

As a result of a general change, it may be necessary to replace a certain component in all or several bills of material (BOMs). This type of change is referred to as a mass change. For more information on how to perform mass changes, see Mass Changes.
