Technical types of BOM

[Former Member]

Hi ALL,

What are the technical types of BOM?...How do we maintain it?

Thanks

Hi Ameya

The R/3 System supports two technical types of BOM to represent similar product variants and production alternatives:

Variant BOMs

A variant BOM groups together several BOMs that describe different objects (for example, products) with a high proportion of identical parts.

A variant BOM describes the specific product variant for each product, with all its components and assemblies.

Multiple BOMs

A multiple BOM groups together several BOMs that describe one object (for example, a product) with different combinations of materials for different processing methods.

The system does not define the technical type automatically. First you must create an additional alternative for or a variant of an existing simple material BOM.

If you define a BOM as technical type "multiple BOM" when you first create a simple material BOM, you can maintain the lot-size fields.

Please note that you cannot change the technical type once you have set it.

How to define the technical type of a BOM:

1. Go to any header detail screen.

2. Choose Edit then More ® Define tech. type.

3. You see a dialog box in which you enter the technical type.

4. Choose Copy.

You see the header screen from which you called the function again.

If you selected technical type "multiple BOM", you see the fields for lot size on the Quantities/long text header detail screen

Dear Amyea,

Please check the following taken from SAP help.

<u><b>Technical Types</b></u>

When you first create a BOM for a material, the system automatically creates the first alternative. The technical type of the BOM is not yet defined, so the technical type is " " (blank). The following graphic shows the structure of a "simple" BOM.

Some companies produce many similar products that have a lot of common parts. To reduce the workload for creating BOMs, you can extend a simple BOM to create a composite BOM, known as a "BOM group".

<u><b>Which Technical Types Exist?</b></u>

The R/3 System supports two technical types of BOM to represent similar product variants and production alternatives:

<u><b>Variant BOMs</b></u>

A variant BOM groups together several BOMs that describe different objects (for example, products) with a high proportion of identical parts.

A variant BOM describes the specific product variant for each product, with all its components and assemblies.

<u><b>Multiple BOMs</b></u>

A multiple BOM groups together several BOMs that describe one object (for example, a product) with different combinations of materials for different processing methods.

<u><b>When do I Create a Variant BOM?</b></u>

The term "variant" refers to changes to the basic model of a product. These changes occur when components are left out or added.

If you are producing several similar products that have a lot of common parts, you can describe these products using a variant BOM. This is the case, for example, if you replace one material component with another to make a different product. Variants can also differ by containing different quantities of a component. You create the new BOM as a variant of an existing BOM.

You can only create a variant BOM from a simple material BOM. No multiple BOM can exist for the material.

A multiple BOM cannot be converted to a variant BOM.

The system does not define the technical type until you create either an additional alternative for a BOM or a different variant for an existing BOM.

Variant BOMs are supported for the following BOM categories:

Material BOMs

Document structures

Equipment BOMs

Functional location BOMs

<u><b>When do I Create a Multiple BOM?</b></u>

One product can be manufactured from alternative combinations of materials depending on the quantity to be produced (lot size). The product is represented by a number of alternative BOMs (alternatives). The differences between the alternative BOMs are only small. Usually the only difference is in the quantity of individual components.

Multiple BOMs are only supported for material BOMs.

The following graphic shows how a product is produced from different components or different quantities using different production procedures.

The multiple BOM contains components, which are only used in one of the alternatives, and one component, which is used in both alternatives.
