Create Bill of Material (BoM) in SAP SD

Tutorial to create, change and display BOM with proper screenshots and step by step process

What is BOM?

BOM or bill of materials is the detailed list of all the raw materials, components, or sub-components required for the manufacture of the finished product. In other words, the bill of materials is the hierarchical arrangement where the finished product is at the top level and all the components, sub-components, raw materials required to assemble or produce the end product at the bottom level.

In BOM we describe which type, what quantity and what size of the material required for an assembly or sub-assembly.

For example:

A bicycle is an assembly of handlebars, frames, wheels, seats, tire rims, paint, headlight, bell, gears etc. So the BOM contains the item number, unit of measure, the quantity of all the materials required for the manufacture of the bicycle.

Types of BOM

There are two types of BOMs:

1. Material BOM

Material BOM (T.Code CS01) is used for the types of materials manufactured in your company.

2. Sales Order BOM

Sales Order BOM (T.Code IB01) is used when products are made as per customer requirements. In order to fulfill the customer requirements, various changes are made in the Sales Order BOM for final product assembly.

Features of BOM

  • Material BOM is normally done in Production Planning, Functional Location BOM and Equipment BOM is used in Plant Maintenance, Order BOM is done in Sales and Distribution and WBS BOM is done in Project System module.
  • We can create either a single-level or multilevel bill of materials as per our requirements.
  • BOM is used for the procurement of raw materials and the production of semi-finished products.
  • As per the material type, size, production method, validity date we can create up to 99 BOM.
  • BOM is also used for standard cost calculation of the finished product by calculating the cost of assembly, sub-assemblies, raw materials, etc.
