BOM & Engineering Change
Multi-level BOMs with effectivity dates, alternates, byproducts, and phantom assemblies — plus a formal engineering change workflow with WIP disposition.
BOMs that match how things actually get built
Revision control, effectivity, and the real-world complications
Multi-Level BOMs
Assemblies, sub-assemblies, piece parts — unlimited depth, cost roll-up, and where-used queries at every level.
Effectivity Dates
BOM items and versions have effective-from and effective-to dates. Build a January part with the January BOM, a March one with the March BOM.
Alternate Parts
Declare qualified alternates per BOM line — MRP picks one automatically when the primary is short, planners can override.
Byproducts & Scrap
Operations and BOMs model byproducts and planned scrap — so cost and material planning both use realistic numbers.
Phantom BOMs
Phantom assemblies resolve through to their components at plan time — you document how the unit is built without creating a ghost stock location.
Where-Used
Pick any part and see every assembly it feeds — critical when evaluating an ECO's impact or a supplier change.
Engineering change, done properly
Formal ECO workflow with approvals and WIP disposition
ECO Lifecycle
Draft → review → approved → released → closed. Every stage transition is logged, signed, and timestamped.
Approval Workflow
Route ECOs to engineering, quality, and manufacturing approvers. Signatures captured, audit trail preserved.
WIP Disposition
For each open job when the ECO releases: rework, scrap, use-as-is, finish-old-revision. Decisions are recorded and enforced.
Effectivity Release
ECO release date drives BOM, routing, and work-instruction effectivity. One release flips the authoritative revision across the whole system.
Impact Analysis
See open orders, in-stock inventory, and active routings that will change before you release the ECO.
Traceability
Every serialized unit links to the exact BOM and routing version it was built with. ECO history is queryable forever.
PLM-grade change control, built in
No extra PLM seat, no integration to maintain. Change control sits with the BOM.
