When do I Create a Multiple BOM?

One product can be manufactured from alternative combinations of materials depending on the quantity to be produced (lot size). The product is represented by a number of alternative BOMs (alternatives). The differences between the alternative BOMs are only small. Usually the only difference is in the quantity of individual components.

Note

Multiple BOMs are only supported for material BOMs.

The following graphic shows how a product is produced from different components or different quantities using different production procedures.

The multiple BOM contains components, which are only used in one of the alternatives, and one component, which is used in both alternatives.

This graphic is explained in the accompanying text

Note

All alternatives of a multiple BOM are stored as a BOM group under one internal BOM number.
You can enter a description to describe all the alternatives of a multiple BOM. You enter this description in the BOM group (BOM header).

As soon as you process one alternative in a multiple BOM, all the other alternatives are locked for processing.

As soon as you process an alternative using a change number, you must use a change number to process all the alternatives in the BOM group.
