    BOM stands for Bill Of Material.

    Bill of materials (BOM)

    1. In the SAP System, you can use BOMs to represent different objects (such as materials, equipment, functional location BOMs, and documents) and to maintain object-specific data.

    2. Document BOM: A complex document may be made up of several documents, such as a program, technical drawings, papers, and photographs. These related information and documentation objects are grouped together as a unit using a document structure – a BOM for a document.

    3. Equipment BOMs are used to describe the structure of equipment and to assign spare parts to equipment for maintenance purposes. Bills of material for functional locations group together the elements of a technical structure, such as the functional unit of an entire plant.

    4. You work with order BOMs when you specially tailor the make-to-order production of your products to the requirements of your customers. In order to meet the customer requirements, sales order specific modifications to various assemblies are often required. Furthermore, assemblies are often specially constructed for a particular sales order.

    5. Before you can create a BOM for the component parts of an object, the object must have a valid master record in your system.

    6. A bill of material that you create for a material is known as a material BOM in the SAP System. A BOM explosion answers the question: What is the product made of? This question arises in various situations, such as when you want to:

    Determine material requirements for a product

    Look at the overall structure of a product in a design department

    See an overview of the parts and materials required

    Calculate the effects of changes to costs

    7. BOM is a collection of materials that make up a product. For example – computer, home theatre system. Material BOM is complex and is dependent on sales and distribution, material management or production planning.

    8. The most important rule is that the material type has to be a FINISHED PRODUCT (FERT) in order to categorise it as a BOM.

    9. BOM processing is divided into two different ways – either at the MAIN item level if the item is assembled or at the sub-item level (i.e. at the component level) if the material is not assembled.

    10. BOM is configured at the item category level (VOV7) and transaction code to create a BOM is CS01.

    11. In case of single level BOM, main item categories TAQ and TAP should represent single level BOM in VOV7 and in case of multi level BOM, the main item categories should represent multi level BOM

    Bill of Material for Empties


    The bill of material for empties (or empties BOM, category 7 in SAP Beverage) defines the assignment between full product and empties. The empties BOM is a special form of the bill of material.

    Properties of empties BOM category 7:

    It is independent of the sales BOM.

    It is also called a group BOM, as it is plant-independent.

    It contains alternate units of measure in the BOM header of the full product (different BOMs for pallets and crates, for example).

    It is integrated in purchasing, inventory management, physical inventory, and logistics invoice verification (automatic BOM explosion).

    In empties BOM category 7, the empties remain an independent material (and therefore have their own info records, condition techniques, evaluations, inventory management, account assignment, and so on).

    The evaluation of vendor deposits is performed using separate info structures.

    Empties can be treated as a valuated (current assets) or nonvaluated (fixed assets) material.

    It provides an overview of the stocks of tied and untied empties at plant and storage location level.

    The empties management uses two different types of bills of material:

    Type 5 (SD BOM)

    This type of bill of material is part of standard SAP R/3. The BOM type is used in SAP SD exclusively.

    Type 7 (Empties Bill of material)

    We recommend: Work with the bill of material type 7 of SAP Beverage in empties management in order to fully use the component. Using this type of bill of material guarantees that the data is generally transferred from SAP MM to SAP SD.


    The BOM components represent a supplement to the BOM header

    The BOM header represents the actual goods

    The BOM components are the assigned empties material

    The bills of material for empties have a separate unit of measure in the header, in contrast to the standard BOMs 1 (production) and 5 (sales). This means, for example, that you can manage different bills of material for a full product in "pallets" and the same full product in "crates". You have to define a bill of material for each unit of measure (bottle, crate, pallet, and so on) that is used in SAP MM and SAP SD. This means the selection during order entry in SAP SD is unnecessary.

    You can only define the empties BOM as a single-level BOM. This means no further nesting is possible within the list.

    Recommendation: To avoid incorrect BOM explosion by the system, always use identical base units of measure in a production order and the corresponding empties BOM.


    The system automatically uses BOM category 7 (empties) during order entry in SAP SD.

    When you create bills of material with different usage categories, it does not matter which ones you create first.

    Please note the priorities in the sequence of BOMs in Customizing.


    A bill of material can group together 10 liters of beer, 1 crate (frame), and the 20 bottles it contains.


    bill of lading (BOL)

    A document issued by a carrier (railroad, steamship or trucking company) which serves as a receipt for the goods to be delivered to a designated person for a shipment. The bill of lading describes the conditions under which the goods are accepted by the carrier and details that nature and quantity of the goods, name of vessel (if shipped by sea), identifying marks and numbers, destination, and so forth. The person sending the goods is the "shipper" or "consignor," the company or agent transporting the goods is the "carrier", and the person for whom the goods are destined is the "consignee". Bills of lading may be negotiable or non-negotiable. If negotiable, for example, payable to the shipper's order and properly endorsed, title to the goods passes upon delivery of the bill of lading.

    This document may also be used to serve as a contract for the transport of cargo.
