BOM Line

The BOM Line object represents an individual component or material required to manufacture a finished product. Each BOM Line belongs to a Bill of Material (BOM) and defines the Product, Stock Item, required quantity, unit of measure, issue method, scrap percentage, and sequence used during the manufacturing process.

A single Bill of Material can contain multiple BOM Lines, each representing a raw material, component, or sub-assembly needed to manufacture the finished product. During production, BOM Lines guide material consumption and ensure the correct components are issued in the proper sequence.

Why is it Used?

The BOM Line object is used to:

  • Define the components required to manufacture a finished product.
  • Associate Products and Stock Items with the parent Bill of Material.
  • Specify the required quantity and Unit of Measure (UOM) for each component.
  • Configure material issue methods during production.
  • Support optional and substitute manufacturing components.
  • Define the sequence of component consumption.
  • Estimate material scrap for production planning.
  • Support multi-level manufacturing structures using Parent BOM Lines.
  • Standardize manufacturing processes across production batches.
  • Enable accurate material planning and inventory consumption.

Key Features

🧩 Component Definition

Defines every raw material, purchased part, or sub-assembly required to manufacture the finished product.

📦 Product & Stock Item Mapping

Links each BOM Line to a specific Product and Stock Item, ensuring the correct inventory item is consumed during production.

🔢 Quantity Management

Stores the exact quantity of each component required for manufacturing one production batch or finished product.

📏 Unit of Measure Support

Supports different Units of Measure (UOM) for accurate material planning and inventory consumption.

⚙️ Material Issue Method

Supports Manual and Backflush issue methods to automate or manually consume materials during production.

🔄 Component Substitution

Allows approved substitute materials when the primary component is unavailable, ensuring production continuity.

⭐ Optional Components

Supports optional components that can be included based on customer requirements or product configurations.

📋 Production Sequencing

Maintains the sequence in which components should be consumed during manufacturing.

📉 Scrap Planning

Defines expected scrap percentage for individual components to improve production planning and material estimation.

🌳 Multi-Level BOM Support

Supports parent-child BOM Line relationships for complex assemblies and nested manufacturing structures.

Checkbox Functionality

The BOM Line object includes checkbox fields that control manufacturing component behavior. 

Checkbox FieldPurpose / Use
Allow SubstitutionAllows an alternative Product or Stock Item to be used during manufacturing if the specified component is unavailable. This provides flexibility in production while maintaining the manufacturing process.
Is OptionalIdentifies the component as optional in the Bill of Material. Optional components can be excluded from the manufacturing process without affecting mandatory production requirements.

Example Business Scenario

Scenario: Adding Components for Sedan Car Manufacturing

Bill of Material Details

  • Finished Product: Sedan Car
  • Finished Stock Item: Maruti Dzire

The following BOM Lines are added:

  • Engine Assembly – Quantity: 1 Each
  • Transmission – Quantity: 1 Each
  • Chassis – Quantity: 1 Each
  • Battery – Quantity: 1 Each
  • Wheels – Quantity: 4 Each
  • Dashboard – Quantity: 1 Each
  • Seats – Quantity: 5 Each
  • Brake System – Quantity: 1 Each
  • Electrical Wiring Kit – Quantity: 1 Each

Each BOM Line is configured with:

  • Issue Method: Backflush
  • Allow Substitution: Disabled
  • Is Optional: No
  • Scrap Percentage: 2%
  • Sequence Number: Based on production order

System Behaviour :

  • Each BOM Line is linked to the parent Bill of Material.
  • Products and Stock Items are associated with individual manufacturing components.
  • Required quantities are maintained for production planning.
  • Components are consumed according to the configured Issue Method.
  • During Production Batch execution, materials are issued based on the defined BOM Lines.
  • Manufacturing follows the configured component sequence.

Outcome:

  • Manufacturing components are accurately defined.
  • Material planning becomes standardized.
  • Production follows approved manufacturing specifications.
  • Inventory consumption is accurate and traceable.
  • Manufacturing errors are reduced through predefined component definitions.
