    Hi Friend,

    By means of BOM usage, you can manage separate bills of material for various internal organizational areas (engineering/design, production, costing, and so on).

    The main differences in the BOM structure result from the different responsibilities in the various organizational areas, which all process different item data.


    In Customizing for MRP, you have defined a sequence for the possible BOM usages for each plant in the IMG activity Define BOM and routing selection using the BOM selection ID.


    The system first searches for a valid BOM or alternative BOM for the BOM usage with the highest priority. If the system does not find a valid BOM or alternative BOM in the selected BOM usage, then the BOM usage with the next-lowest priority is selected. The system then looks for valid BOMs for this BOM usage.

    Many companies have only one universally applicable BOM structure for all areas of their company. This structure usually takes the form of complete single-level BOMs, created in the design department, and used in both material management and the assembly workshop.

    The R/3 System allows you to maintain individual BOMs for any area of your company. These BOMs are maintained independently of each other and are assigned different internal BOM numbers. In this way, each area is only dealing with the specific data it requires.

    In Customizing for Production, define individual BOM usages for the different areas within your company by choosing Basic data ® Bill of Material ® General data ® BOM usage ® Define BOM usages.

    You can define BOM usages for the following scenarios:

    You maintain separate BOMs for different areas within your company, such as design or production.

    You create just one BOM for all areas within your company.
