Introduction
In the complex landscape of manufacturing and production, the Bill of Materials (BOM) serves as a critical foundation for product lifecycle management. The BOM encapsulates a comprehensive list of raw materials, components, and instructions necessary for constructing a product. A pivotal aspect of BOM management is the establishment of number ranges, which are essential for categorization, tracking, and differentiation of parts within various modules.
This document aims to elucidate the process of creating BOM number ranges using transaction codes CS90, CS91, IB91, and IB90. It will delve into the nuances of each transaction code, their unique applications, and the significance of segregating number ranges based on distinct categories. Through this educational manuscript, we will explore the rationale behind the separation of number ranges and the benefits it brings to the organization's operational efficiency.
The Necessity of Number Range Differentiation
Number ranges in BOM are not merely a sequence of numbers; they represent a systematic approach to classifying components that can have profound implications on inventory management, cost calculation, and production planning. Differentiating number ranges by categories—such as type of material, usage in production, or procurement type—enables a more granular control over the BOM structure.
Transaction Codes: A Comparative Analysis
• CS90 (Create Material BOM): This transaction code is utilized for creating material-specific BOMs, which are tailored for individual materials and their unique assembly requirements.
• CS91 (Create Standard BOM): In contrast, CS91 is employed for standard BOMs that apply to multiple materials, serving as a template for common parts or processes.
• IB90 (Create Equipment BOM): IB90 is designated for equipment BOMs, focusing on the assembly of equipment and the corresponding parts specific to machinery or plant maintenance.
• IB91 (Create Functional Location BOM): Lastly, IB91 is used for functional location BOMs, which are crucial for site-specific assemblies and maintenance activities.
Configuring Number Ranges with Visual Aids
The document will further include visual aids to demonstrate the configuration settings for each transaction code. These images will serve as a practical guide for users to navigate through the SAP interface and effectively set up their BOM number ranges.
