Material BOM Browser
Definition
Navigation tool for displaying the multi-level BOM of a material
Use
You use the material BOM browser to navigate in a multi-level material BOM.
Structure
In the material BOM browser, the multi-level BOM is displayed similarly to in the
product structure browser. This means you see an overview tree, whose branches you can show and hide. As opposed to the product structure browser, in the overview tree of the material BOM browser, only the BOM headers and items are displayed.
