Alternate BOM and routing
In this section you can enter values for Finish date (today's date is entered by default), Order number, Customer, Variant code and Warehouse, which can affect the BOM and routing structure concerning the different terms. However, the Revision term is not available here, since revision can differ for the parts. It is always the part's active revision that is used in the structure explosion. The Warehouse term is only available if that option is installed.
If you in the BOM and routing, e.g., have selected that one material should replace another material for a certain customer and you here have selected that customer, this means you will get a different BOM and routing structure in the list. If you leave the customer field empty, the BOM and routing structure will not use that term.
