# BOM Tutorial

Bill of Materials (BOM) management is a core functionality in any modern manufacturing or logistics environment. Its versatility and configurability make it fundamental for ensuring traceability, operational efficiency, and manufacturing flexibility.

In this tutorial, you will find a series of simple, guided use cases designed to help you better understand how each **BOM** functionality works and how to configure it according to your specific processes.

The main topics covered are:

1. [[tutorials-bom-assembly-operations-index]]

      - **Explicit, Automatic and Mixed Assemble**. In this section, we explore different types of assembly logic:
        - Explicit - components are assigned manually during assembly.
        - Explicit Add - similar to explicit, but focuses on incremental **Material** quantity, and is only possible if the material is tracked in with quantity zero.
        - Explicit Long Running - used for continuous assembly processes.
        - Automatic at Track-In or Track-Out - components are automatically assigned at specific production events (start or finish of a step).
        - Mixed - when, for the same step, manual and automatic assemblies can occur.

      - **Replace and Disassemble Operations**. Here you will learn how to manage changes and reversals in assemblies. This includes:
        - Replace - swap components in use.
        - Disassemble - reverse a full or partial assembly, restoring component status.

2. [[tutorials-bom-quantity-variations]]

      This section focuses on the different ways to define and control BOM Item quantities, including:

      - Dependent on main **Material** quantity - configure component consumption relative to the produced quantity of the item.
      - Fixed quantity - define components that are always used in a fixed amount, regardless of production size.
      - Negative quantity (by-products) - register outputs such as waste or by-products using negative values.
      - Reference items - Include components for informational or documentation purposes, without **Material** consumption in MES.
      - Option to capture information - allows the user to capture information with or without consuming **Material** quantities.

Other topics, such as BOM Explosion and BOM Variants, are features related to different entities and are explored in subsequent tutorials:

## How to Use This Tutorial

Each topic is accompanied by practical examples, detailed step-by-step instructions, and configuration tips to help you avoid common mistakes. By the end of this tutorial, you should be able to:

- Understand the individual **BOM** functionalities.
- Recognize their operational impact.
- Configure them within your system.
