Creating a Material BOM

Procedure

After you a create a BOM for different segmentation values, the same BOM is listed in the production order based on different stock segments. You can view only those components which were included when BOM was created for a particular stock segment.

Follow these steps to create a material BOM:

On the SAP Easy Access Menu, choose Logistics Production Master Data Bills of Material Bill of Material Create and enter the required data. On this screen, you maintain data that identifies the bill of material, as well effectivity data.
Alternatively, you can use the transaction CS01 to create a material BOM.
In the Material field, enter the material for which you want to create the BOM. If you do not know the material number, you can use the help (F4).
Enter a Plant.
If you want the BOM to be effective in a specific plant, enter the plant. You can allocate the BOM to additional plants if required.
Enter a BOM Usage.
If a parameter is defined in your user master record as a default value for the Usage field, the system enters this default. When you select a BOM usage, you define the maximum range of item statuses that can be assigned to all items in the BOM. For each usage, you can only maintain certain item status indicators.
When you create a simple BOM, you do not need to enter an alternative.
- If you do not make an entry when you first create a BOM, the system automatically creates alternative 01
- If you already know when you first create a BOM that you want to extend the BOM to make a multiple BOM, and that this alternative is not alternative 01, enter an alphanumeric value.
Enter a change number if you want to associate the modified structure to an identifier. You can later view that change by specifying the change number.
Press Enter to go the Item Overview page.
Enter the Item Category of the BOM. This field is used to control field selection, default values for BOM maintenance, triggering of specific system activities, and so on.
In the Component field, enter the material number of the components that you specify as part of the BOM.
Enter the Quantity of the component.
Enter the Unit for the component quantity.
Select one or more components and click the (Segmentation) button to enter the segmentation values for a material.
In the Component Selection by Segmentation screen, enter the following fields:
1. Segmentation Value: Click the Fast Entry button to enter a segmentation value.
2. Include Segment Value: Select this checkbox if you want to include the segment value in the header of a material. If you select this checkbox for one segment value of the header material, the system automatically excludes all other segment values.
  Note
  You can also double-click on a component to add a segment value.
  
  This field is used to set the requirement segment for a component in a planned and production order (during BOM explosion) and is enabled based on the following conditions:
  Header material is not segmentation relevant.
  Scope of segmentation strategy for header material is 2 (only requirement segmentation).
  Scope of segmentation strategy for a component material is 1 (stock and requirement segmentation) or 2 (only requirement segmentation).
  Scope of segmentation strategy for a header component is 1 (stock and requirement segmentation) and the quantity is negative (if the output material is a by-product).
  End of the note.
3. Exclude Segment Value: Select this checkbox if you want to exclude the segment value in the header of a material.
Click Accept to confirm the changes.
