What Is BOM In SAP?

Are you curious to know what is BOM in SAP? You have come to the right place as I am going to tell you everything about BOM in SAP in a very simple explanation. Without further discussion let’s begin to know what is BOM in SAP?

In the world of enterprise resource planning (ERP) software, SAP (Systems, Applications, and Products) is a renowned platform that offers comprehensive solutions to businesses across various industries. One crucial feature of SAP that significantly impacts manufacturing processes is the Bill of Materials (BOM). The BOM is a foundational element in SAP’s Material Management (MM) module, enabling organizations to streamline their production, inventory, and procurement operations. In this blog, we will explore the concept of BOM in SAP, its key components, and its role in supporting efficient manufacturing processes.

What Is BOM In SAP?

In SAP, a Bill of Materials (BOM) is a structured list of components, sub-assemblies, and raw materials required to manufacture a finished product. It serves as the foundation for production planning, allowing businesses to understand the composition of a product and the relationships between its parts. The BOM also includes information on the quantities of each component needed, as well as their respective units of measure.

Key Components Of BOM In SAP

  1. Header: At the top of the BOM hierarchy is the header, which contains general information about the finished product, such as the product code, description, and unit of measure. The header also stores data related to the validity of the BOM, providing details on when the BOM becomes effective and when it is no longer valid.
  2. Items: The BOM items constitute the individual components, assemblies, or materials that make up the finished product. Each item is associated with a unique item number, allowing easy identification and referencing. The items also include details like material codes, descriptions, and the required quantities for production.
  3. Item Category: In SAP, each BOM item is assigned an item category that classifies it based on its function in the production process. Common item categories include components (materials directly used in production), assemblies (sub-products combined to create the finished product), and phantom items (used for grouping components without physical existence).

Types Of BOM In SAP

SAP offers several types of BOM, tailored to various manufacturing scenarios:

  1. Engineering BOM (eBOM): The eBOM, also known as the design BOM, represents the idealized structure of a product during the design and development phase. It includes all the necessary components to create the product, even those not intended for procurement or production.
  2. Production BOM (pBOM): The pBOM is a practical BOM used for manufacturing purposes. It includes only the components and materials that are necessary for the actual production process, excluding any non-manufacturable elements present in the eBOM.
  3. Sales BOM (sBOM): The sBOM is used primarily for sales and distribution purposes. It represents a simplified version of the BOM, showcasing the product structure without revealing too many technical details.

Significance Of BOM In SAP

  1. Accurate Production Planning: BOM enables businesses to plan production accurately by outlining the required components and their quantities. This helps optimize inventory levels, reduce lead times, and ensure a smooth production process.
  2. Cost Estimation: SAP’s BOM functionality assists in calculating the cost of the finished product by considering the costs associated with each component and assembly in the BOM. This data is crucial for pricing decisions and cost control.
  3. Efficient Procurement: With the BOM, procurement teams can easily identify the materials needed for production, allowing them to streamline procurement processes and maintain adequate stock levels.
  4. Variant Configuration: SAP’s variant configuration feature allows businesses to manage multiple product variants within the same BOM structure. This capability is beneficial for industries that produce customizable or configurable products.


The Bill of Materials (BOM) is a fundamental aspect of SAP’s Material Management module, empowering businesses to effectively plan, execute, and control their manufacturing processes. By providing a comprehensive view of the components and materials required to create a finished product, BOM optimizes production, streamlines procurement, and enables accurate cost estimation. As SAP continues to evolve and cater to the diverse needs of modern industries, the BOM functionality remains a critical tool for businesses to enhance productivity, efficiency, and competitiveness in the global market.


What Is BOM For Material SAP?

A bill of material (BOM) is a list of materials, assemblies, components, and parts required to manufacture a product. These can be used to define simple relationships where one component comprises several subcomponents. If required, you can define a maximum and a minimum quantity for each material and class in the BOM.

What Is An Example Of A BOM?

A BOM is sometimes referred to as a product structure, assembly component list or production recipe (in process manufacturing industries). For example, if a bicycle manufacturer wants to build 1,000 bicycles, the bill of materials will consist of all the individual parts needed to build the bicycle.

What Are The Types Of BOM In SAP?

Depending on your production process needs, you can create 4 types of BOMs in SAP Business One.

  • Production Bill of Materials.
  • Sales Bill of Materials.
  • Assembly Bill of Materials.
  • Template Bill of Materials.

Why Is BOM Used In SAP?

SAP bill of materials (BOM) is one of the elements of SAP PP master data which contains information like list of components and their quantities required to produce an assembly or a finished good (FG).
