In SAP S/4HANA, a "multiple BOM" refers to alternative BOMs (transaction CS01, field: Alternative) for the same material, allowing different component combinations. Reasons for these variations include:
* Manufacturing date(A): Alternative BOMs can have different validity periods (Valid From/To dates in CS01 header). For example, a new BOM might replace an old one due to design changes effective from a specific date, resulting in different components based on when production occurs (checked in MRP or CO01).
* Lot size(D): Each alternative BOM can specify a lot size range (CS01, header data, field: Lot Size From
/To). Different component combinations might be optimal for small versus large production runs (e.g., bulk packaging for larger lots), leading to distinct BOMs tied to quantity.
BOM header status(B) (e.g., Active/Inactive) controls usability but doesn't define component combinations- it's a single status per BOM.BOM component status(C) isn't a standard field-component relevance is managed via item category or deletion flags, not status, and doesn't explain multiple BOMs. This is per SAP's multiple BOM functionality.
