In SAP a BOM stands for Bill Of Material.

A Bill of Material is a list of all the materials (and their quantities) that are required for making or assembling a product.

The BOM is used in discrete manufacturing and production planning.

BOM structure

  • Header – contains identifying data like the name, material, warehouse, revisions, type, etc.
  • Item – specs on each component needed including item number, description, quantity, category, etc.
  • Sub Items – used to describe partial quantities and installation points
