Answer

What is BOM management?

BOM management is the disciplined control of a product’s bill of materials — components, quantities, levels, versions, substitutes, and engineering changes — so planning, purchasing, production, and costing all explode the same structure. In FOS ERP, BOMs sit at the centre of MRP and work orders rather than in disconnected spreadsheets.

What a manufacturing BOM must hold

Depth for discrete and engineer-to-order plants — not a flat parts list.

01 Structure

One product, many levels.

Multi-level BOMs & quantities.

Parent assemblies nest sub-assemblies and bought-outs with precise quantities and units. Multi-level structures let MRP net demand at every leaf while production issues against the right level of the tree.

  • Parent–child levels for assemblies and phantoms
  • Quantity and UOM per component line
  • Clear link from finished good to raw material
FGMachine assemblyLevel 0 · qty 1Active
SAFrame sub-assemblyLevel 1 · qty 1BOM
RMMS plate 12mmLevel 2 · 24 kgLeaf
02 Control

Change without chaos.

Versions, substitutes & engineering changes.

Versioned BOMs keep historical builds auditable when drawings change. Approved substitutes protect supply when a primary item is short. Engineering change records document what moved, when, and which open orders should follow the new revision.

How BOMs drive planning & production

BOM depth here; execution and netting live in the connected modules.

Routing relationship

BOMs define what is consumed; routings define where and in what order operations run. Together they give work orders a complete build plan.

Costing

Component costs roll up through the structure so estimates and job costing reflect the same BOM revision production will build.

Planning (MRP)

Planning & MRP explodes sales demand against the active BOM, nets stock, and raises purchase and work proposals.

Production usage

Production issues material and tracks WIP against the BOM lines attached to each work order — not a parallel spreadsheet kit list.

Frequently asked questions.

Top questions about BOM management software — answered for manufacturers in India.

What is BOM management?

BOM management controls a product’s bill of materials — components, quantities, levels, versions, substitutes, and engineering changes — so planning, purchasing, production, and costing explode the same structure.

What is a multi-level BOM?

A multi-level BOM nests sub-assemblies under a finished good so MRP can net demand at every leaf and production can issue against the correct level of the product tree.

Does FOS support BOM versions?

Yes. Versioned BOMs keep historical builds auditable when drawings change, with effective timing so open work follows the correct revision.

Can we define substitute components?

Approved substitutes protect supply when a primary item is short, while keeping the active BOM controlled for planning and costing.

How do engineering changes relate to BOMs?

Engineering change visibility documents what moved in the structure and which open orders should follow the new revision, reducing informal drawing updates on the floor.

How do BOMs connect to MRP?

Planning and MRP explode sales demand against the active BOM, net stock, and raise purchase and work proposals from the same product structure production will build.

How do BOMs connect to production?

Work orders pull material lists from the BOM attached to each order so kit issues and WIP tracking match engineering definition — not a parallel spreadsheet.

Does BOM management include costing?

Component costs can roll up through the structure so estimates and job costing reflect the same BOM revision used on the shop floor.

How is BOM management different from the full Planning page?

This page focuses on product structure depth — levels, versions, substitutes, and ECOs. Planning and MRP cover netting, proposals, and shortage-driven replenishment.
