While a Variant BOM groups together several BOMs that describe different objects (for example, different models of a car) with a high proportion of identical parts, a Multiple BOM groups together several BOMs that describe one object (for example, a product) with different combinations of materials for different processing methods. The Variant BOMs are supported for the following BOM categories:
- Material BOMs
- Document structures
- Equipment BOMs
- Functional location BOMs
Multiple BOMs are only supported for Material BOMs.
