The material BOM of material A contains components B and C, which are assemblies. The material BOM of material B contains components D and E. Component D has 2 variants that have dependencies. According to the values assigned in the sales order, only one of these variants is used. Similarly, component E has 3 variants. The following graphic shows this BOM as a multi-level super BOM with all variants.

You fix the assembly. When you save the configuration result, the system generates an order BOM for material B. If Result-oriented BOM is set in the configuration profile of the configurable material, the system only creates the components that are used in the order BOM (see Creating a Result-Oriented BOM). If this indicator is not set, the system creates an order BOM that contains all components of the super BOM and the local dependencies as a copy, referencing all other data (see Creating a Knowledge-Based BOM).
