BOM comparison

What changed?

  • Which lines were added or removed?
  • Which quantities or revisions changed?
  • Which structure is current?

DeltaLedger impact analysis

What does the change mean now?

  • What is already financially committed?
  • Which inventory and builds become vulnerable?
  • Which decisions reduce exposure?
  • What remains unresolved—and why?

What is driving the exposure?

The largest driver is the open commitment for APX-8801B. Its cancellation position remains estimated until Northstar’s terms or written response are recorded.

Start without an integration project

One change. Two exports. One defensible decision.

Begin with a current and proposed BOM plus an open-PO export. Add inventory, WIP, supplier terms, and effectivity evidence as the decision requires it.

Questions buyers ask

Clear answers before you begin.

What is BOM change impact analysis?+

BOM change impact analysis identifies the downstream inventory, work in progress, purchase orders, suppliers, production timing, and financial decisions affected by a product-structure revision.

How is this different from comparing two BOMs?+

BOM comparison identifies added, removed, and changed lines. DeltaLedger follows those lines into operating commitments and records the evidence needed to make and defend the resulting decision.

Does DeltaLedger become our master BOM system?+

No. Your PLM, ERP, or controlled product records remain authoritative. DeltaLedger uses relevant change evidence to evaluate downstream exposure.

Can DeltaLedger distinguish an addition from a replacement?+

Yes. Additions and removals are calculated from the imported structures, while one-for-one replacement relationships require explicit human review instead of being silently inferred.

Can the analysis include effectivity timing?+

Yes. Teams can compare immediate, date-based, and inventory-runout scenarios and preserve the chosen effectivity decision with its evidence.
