A released bill of materials is changed by a change order with a date, an approval and an impact assessment — never by editing the structure underneath the orders already planned against it.
Impact Analysis, Change Register and BOM Change History
Before a change is released you can see what it touches: which orders are already open against the affected lines, and a decision recorded per order about what should happen to it.
- Change register with search and filters, plus a detail view of everything a change proposes
- Change history on the BOM itself — what changed, when it took effect, and under which change order
Engineering Change Orders for Bills of Materials
Once a BOM is released, production orders, purchase orders and budgets have been planned against it. Editing it in place changes what those documents were costed on, silently. A released structure is now changed only through an Engineering Change Order.
- Draft, submit, approve, reject or cancel a change, and raise a counter change that stages the exact inverse
- Release either by line effectivity (end-date the old line, start the new one) or as a new version of the structure
- Every change carries a category and an effective-from date, so which BOM applies on a given day is a single, unambiguous answer
- If somebody moved a field underneath the change while it was in flight, the release is refused and the field named — it is never silently merged
- There is deliberately no un-release: a release has a date, and work has been planned against it
Bills of Materials Are Now Permission-Gated
The BOM endpoints previously required only a signed-in user, so any user of the tenant could create, edit or delete any BOM at any plant. They now require explicit BOM permissions, and two focused roles ship with the feature: BOM Engineer (authors and raises changes) and Engineering Change Approver (approves, releases and decides impact).
Administrators: review role assignments as part of this upgrade so the BOM screens stay available to the people who need them.
