You can break down large and complex product structures into a number of related units. Each unit can be represented by a BOM, referred to in this documentation as a single-level BOM.

A single-level BOM describes one or more assemblies by means of component quantities. In the following, the term single-level BOM will be shortened to BOM.

In practice, a single-level BOM is often a collection of standardized assemblies. A single-level BOM can be either a complete machine or an individual part.

You can use single-level BOMs to define one-time solutions for recurring tasks. Once you have defined your solution in the form of a single- level BOM, you can use it whenever you need it and combine it with other BOMs as required.
