A bill of materials (BOM) is a list of items used to perform maintenance activities. There are different types of BOMs, as they are often called but, in maintenance functions, we generally use equipment BOMs. This material list is created in a hierarchal manner and associated with one specific piece of equipment. BOMs can also be created for functional locations, making it efficient to select materials.
The second type of BOM is associated with a material type called an IBAU. This is a maintenance assembly list created by using individual parts tied to a higher-level material instead of an equipment master or functional location.
Creating a good BOM can be a critical factor in completing work for a piece of equipment. It will, at a glance, make it possible to identify the materials needed to service that piece of equipment.
In the following example, you will learn how to create a bill of material and how to display it in your work order.
Enter the equipment master number for the bill of materials you wish to create, plant code, and BOM usage 4 (plant-maintenance usage), and the date you wish to make your BOM valid from.
Click the enter button.
Add the following information
• ICT: This indicates the status of the material, i.e., stock (L), non-stock (N) or text (T).
• Component: This is your material master number.
• Quantity: Number of components needed to service the equipment
• UN: Unit of measure for how you receive the material
Once finished, click the save button.
You will have the ability to see the new materials on the BOM you created under the functional location in which the equipment is installed (transaction IH01).
When creating a maintenance work order for the equipment, pull up the materials on the BOM by using the list button on the components tab of the work order.
This automatically lists the materials on the BOM. Select the check box for the materials that you wish to carry into your work order. Click the green check mark.
Your materials populate in your work order.
Note that a ritual should be built around updating your BOMs on a frequency. This allows new materials, or materials with different specifications, which will also have a new material master number, to be added and any materials no longer applicable to be deleted. This can be completed in transaction IB02, change bill of materials. MT
