SAP MM: Bill of Material

Bill Of Material In Sap Mm

A Bill of Material (BOM) is a crucial component in the SAP MM module. It serves as a comprehensive list that outlines all the materials required to manufacture or assemble a product. The BOM provides detailed information about each material, including its quantity, unit of measure, and where it is used within the production process. This article will delve into the concept of BOMs in SAP MM and explore their significance in managing inventory, procurement processes, and production planning.

How to create BOM

To begin, access the CS01 transaction from the SAP Easy Access screen.

1. Input the main material for which a Bill of Material (BOM) is to be generated.

2. Specify the Plant Code.

4. Indicate the effective date from which the BOM will be valid.

Once you have completed all the required fields, simply click or press Enter to proceed to the next screen.

2. Input the code for the component material in the designated field.

3. Specify the quantity of the component according to the given instructions.

4. The system will automatically retrieve certain details such as description and unit of measure for the component after clicking or pressing enter on your keyboard.

To access more detailed information about a specific component in the Bill of Material (BOM), you can double click on the corresponding entry within the Assembly column. If the checkbox is not selected, it means that there are no additional levels of BOM for that particular component.

To view the BOM header, simply click on the designated icon. The system will subsequently display the BOM header screen for you to access in the following step.

1. Enter the quantity of the main material. If it is 1 EA (each), then the component quantity will indicate how much is required to produce one item.

2. Save the newly created Bill of Material by clicking on the appropriate button, and a system message will be displayed at the bottom left corner.

Moving forward, we will now explore the process of modifying a Bill of Material (BOM).

Creating a bill of material in SAP MM: A step-by-step guide

To create a BOM, you need to follow these steps on the SAP Easy Access Menu:

1. Go to Logistics Production Master Data Bills of Material Bill of Material Create.

2. Enter the material for which you want to create the BOM in the Material field.

3. Specify a Plant where the production will take place.

4. Choose an appropriate BOM Usage, which defines how this particular BOM will be used.

By entering these required data fields accurately, you can successfully create a Bill of Material for your desired product in SAP MM system.

Changing BOM in SAP MM: A Guide

In the event of any modifications to the list of components or their quantities required for producing the end product, we would make necessary adjustments to the Bill of Material (BOM).

To begin, access the CS02 transaction from the SAP Easy Access screen.

1. Input the main material for which the Bill of Material (BOM) requires modification.

2. Specify the Plant Code.

4. Provide a valid from date, indicating when the BOM will become effective.

Step 2) Once you have completed entering the necessary information, proceed to the next screen by clicking on the designated button.

Modify the code or quantity of the component. Once all changes are made, save the Bill of Material (BOM) and a notification will appear indicating that it has been updated.

Understanding BOM Master Data in SAP

Overall, BOMs help keep track of all the materials needed for production, while work plans provide instructions on how to assemble those materials. These are crucial pieces of information for managing both materials and production processes effectively in SAP MM.

Displaying Bill Of Material in SAP MM

To begin, access the CS03 transaction from the SAP Easy Access screen.

1. Input the main material to view its Bill of Material (BOM).

2. Specify the Plant Code.

4. Indicate the effective date, which determines when the BOM becomes valid.

Step 2) On this screen, you will see a display of the components and their respective quantities.

To view the Bill of Material header, simply click on the icon.

In the third step, you will be able to view the BOM header information.

  1. Display base quantity of product

Sometimes, users mistakenly attempt to create another BOM for the same product in SAP MM. However, when they receive a warning message stating that an alternative BOM2 is being created, they often ignore it and proceed anyway. This can result in unnecessary duplication of data with multiple alternative BOMs for the same product. It is crucial to pay attention to these warning messages and prevent such duplicate entries from occurring.

The SAP module for bill of materials

SAP BOM is one of the most critical elements of the SAP Production Planning (SAP PP) module, allowing users to create a list of the components and their quantities required to produce a final product or assembly and making it easier to save BOM components for future use.

The SAP code for BOM

Log in to SAP. Type transaction code CS01 for creating a new BOM (or CS03 for displaying an existing BOM). Click into the field “BOM usage”.

The meaning of CS01 in SAP MM

CS01 is a crucial master data transaction in SAP MM that allows users to maintain the Bill of Material (BOM) for header materials. The BOM consists of a list of components or parts required to produce the main item. Without maintaining this information in CS01, an issue may arise during sales order creation when attempting to add the main item. A pop-up notification will appear stating that no valid Bill of Materials has been found for the entered material. Consequently, further processing of the order may not be possible.
