EBOM vs Mbom

Currently Being Moderated



Can anyone tell me something about Ebom vs Mbom.

I want repliies with regard to manufacturing.


Thanks & Rgds,

    Hi Pareena...


    Reply to ur Query is:


    Proplanneru2019s eBOM (product engineering bill of materials) defines and manages the components and structure of the product being manufactured. Users can attach documents to components (CAD Files, Cost Studies, etc), as well as database attributes that are reference by the other planning modules.

    Users can import bill of material directly into the eBOM, and then export the eBOM items into mBOM to populate the manufacturing bill of material for the first time. When the eBOM is reimported in the future, Proplanner will reconcile and report on differences between the new eBOM and prior mBOM.

    The eBOM and mBOM are presented as assembly trees that depict a hierarchical structure for the assemblies, subassemblies, and parts that make up the product, whether purchased or manufactured. Users can create and modify these trees as they would with files in Windows Explorer.

    Whether created or imported, components are stored in the customeru2019s library for easy reference by others in the organization.

    All end-items, assemblies, purchased components, manufactured components and raw materials are identified in the eBOM. Product features, can be accounted for in the mBOM. Users can associate drawing files, PDFs, digital photos and even video to every component in the tree for easy reference.

    The eBOM allows users to assign suppliers to Purchased parts, raw materials and manufactured components that can have external suppliers.

    Components in the eBOM can be assigned version numbers and are thus reconciled with the mBOM based upon their version.

    Proplanner allows users to assign Options to the eBOM components and Option Mixes to the eBOM end-items. Users can then generate a specific eBOM view for a particular model, or display the generic view which lists all components used in all models.

    Hi pareena,


    EBOM's are design/engg BOM's.

    MBOM'S are manufacturing BOM's.


    Generally the design (EBOM) and the manufacturing (MBOM) views of the BOM are different, as each discipline has different needs and definitions as to how they structure and use a BOM. For example, the MBOM may contain phantom parts or made-on-assembly parts that do not exist in the EBOM view. EBOM's are used for the engineered products manufacturing i.e; designing a new product(for example).

    hi pareena,


    e bom means engineering BOM

    mbom is manufacturing BOM


    One of the functions of such software is the configuration of bills of materials or BOMs, taking the component parts list from engineering (eBOM) and manufacturing (mBOM) and updating it from “as delivered” through “as maintained” to “as used”.


    when the production planning department creates the Production Bill of

    Materials (PBOM) based on the Engineering Bill of Materials (EBOM). This

    initiates a planned order, which in turn creates a material need. The planned

    order is then transformed into a production order by the production controller

    in the workshop. This is done in SAP in transactions MD04 and CO41. The

    production order is then released with the transaction CO02. Here, the

    system automatically creates a picking list. Next the production order

    operation is confirmed by the production controller or supervisor in

    transactions CO11N and CO15.

    This is the critical point where it needs to be checked whether some materials

    went on the goods movements with errors list (COGI list). These could be

    materials that are consumed from stock or the end product itself. Mostly it

    concerns only the materials that are consumed from stock. Errors occurring

    in the consumed materials do not prevent the end product from being

    completed but it will have two unwanted consequences: the stock balances

    will become distorted and the costs will not be registered on the production

    order correctly.









    1) The recomended way of check-in file into SAP Content server is through CAD Desktop.

    Goto CAD Desktop and check in the file using Check in Original.

    If the Original file is not checked in SAP then the Problem is in File Check-in.


    2) Create EBOM and save in SAP. If you are getting any problem. Then the Problem is with BOM Creation
