What is BOM table and the role of BOM in ERP system


What is a BOM table? Bill of Materials (BOM), also known as product structure table or product structure tree; in some industries, it may be called "recipe", "element table" or other names. In ERP system, the word material has a broad meaning, it is the collective name of all products, semi-finished products, work in progress, raw materials, supporting parts, collaborative parts, consumables, etc. and production-related materials. product design, and more. The system can use a variety of methods to describe the bill of materials, such as the single-level method, indent method, module method, pause method, matrix method, and cost method, etc.

BOM is the most important basic data in ERP system, its organization format design and reasonable or not directly affects the processing performance of ERP system, so it is very important to design reasonable and effective BOM flexibly according to the actual usage requirements. In addition, BOM is also an important interface between CIMS/MIS/MRPⅡ/ERP and CAD, CAPP and other subsystems, which is the key to system integration. Therefore, when implementing BOM management by computer, the information exchange between it and other subsystems should be fully considered.

BOM information is used in ERP system for MRP calculation, cost calculation, inventory management, BOM has various forms, these forms depend on its use, the specific use of BOM are.

1、 It is the basis for computer identification of materials.

2、 It is the basis for planning.

3、 It is the basis for matching and receiving materials.

4、 It is the basis for tracking the processing process.

5、 It is the basis of purchasing and outsourcing.

6、 It is the basis for cost calculation.

7、 It can be used as a reference for quotation.

8、 To carry out material traceability.

9、 Make the design series, standardization and generalization.

The use of Bom table can be divided into seven categories, mainly:

1、The basis for the planning department to prepare the plan When the company receives an order, the planning department will follow the delivery date of the order, combined with Bom and inventory information, the order progress review, so as to prepare the production plan.

2, the procurement department procurement of materials based on Bom information, the procurement department can be timely, appropriate amount of procurement of materials to avoid excess or shortage of inventory phenomenon. It can also save a lot of time for the pre-purchase preparation work, make the procurement cycle more abundant, and ensure that the materials can be procured back in time. In addition, the detailed description of code model and other related descriptions in Bom makes the procurement materials clear at a glance and does not occur the phenomenon of Zhangjiaosi.

3、The basis for logistics department to issue materials With Bom, logistics department can directly issue materials according to the material code and quantity of materials in Bom, which is convenient and fast and can greatly improve the efficiency and quality of work of material custodian.

4、The financial department can calculate the cost of the basis of the financial department through Bom can clearly calculate the cost of materials required for each product small assembly in the manufacturing process, so as to carry out cost control and avoid unnecessary waste.

5、Reference for the technical department to reduce the product cost The technical department carries out cost reduction work according to Bom against the corresponding unit price of materials.

6、The important document for arranging production line can be clearly seen from Bom whether a certain material is assembled in chassis workshop or in final assembly workshop, and specifically in which station, so that production scheduling can easily refer to BOM to arrange production.

7, the basis of the sales department bidding quotation bidding work is focused on the price, the specific product configuration corresponding to the cost can be calculated through the Bom, to provide the basis for bidding quotation. bom import and management combined with the actual operation of the company, the Bom import into the pre-work and fast import two parts, the Bom management is divided into audit, modification and permission three parts.

BOM is the most important basic data in PDM/MRPⅡ/ERP information system, its organizational format design and reasonable or not directly affects the processing performance of the system, therefore, according to the actual use of the environment, flexible design of reasonable and effective Therefore, it is very important to design a reasonable and effective BOM according to the actual usage environment.
