Bill of Materials (BOM)

Extract hierarchical part structures and quantities from bills of materials and parts lists.

The Challenge

BOMs are multi-level indented structures mixing part numbers, descriptions, quantities, units and references, often exported as PDF or embedded in drawings. Maintaining the parent-child hierarchy during extraction is the key difficulty.

Industries

Manufacturing, machinery, automotive, electronics, plant engineering.

Who Uses It

Engineering, procurement, production planning, ERP/PLM integration.

BASE Schema

Assembly / product — Text

BOM level — Quantity

Part number — Text

Description — Text

Quantity per level — Quantity

Unit of measure — Enumeration (pcs, kg, t, m, m², m³, l, h)

Reference designator — Text

Make/buy — Text

Recommended pipeline settings — Context (part-number conventions and phantom assemblies)

OPTIONAL Validation

Hierarchy integrity (every child has a parent); part-number format checks; quantity roll-up consistency; mapping to item master.

Frequently ASked Questions

How can AI digitise a bill of materials from a PDF?

It extracts every part line with its level, quantity and reference, preserving the parent-child hierarchy, ready to import into ERP or PLM.


Can BOM extraction preserve multi-level structures?

Yes — the indentation and level relationships are reconstructed so the assembly hierarchy stays intact.


Why automate BOM digitisation?

It removes error-prone manual entry of large parts lists, speeds quoting and procurement, and syncs engineering with ERP.
