Analyzing BOMs

Objective

After completing this lesson, you will be able to perform BOM evaluations

BOM Reporting

You perform a BOM evaluation when you are interested in the requirements for a product, the overall structure of a product or the necessary parts and materials.

The following are examples of situations in which you need to know what a product consists of:

  • You need to determine the requirements for a product.
  • The engineering design department needs to look at the overall structure of a product.
  • You need an overview of all the necessary parts and materials.
  • You need to calculate costs or effects of cost changes.
A BOM explosion can be level-by-level, multilevel or summarized.

The BOM application defines the following criteria for the search procedure:

  • Priority of the BOM where-used list
  • Priority of a specific alternative for a particular multiple BOM
  • Production versions in the material master
  • Checks for particular status indicators

In your user master record, you can enter a default value for the BOM application field. This value is the SET- / GET-parameter CSA.

Where-Used Lists

The where used list can be used for Work Centers, Capacities, PRTs, Materials or Documents.

You can create where-used lists for the following:

  • Work centers
  • Capacities
  • Production resources/tools
  • Reference operation sets
  • Materials
  • Documents

You can use the object overview to select the list you require.

Single-Level and Multi-Level Material Where-Used Lists

Whenever a multilevel BOM was created, it is necessary to display and evaluate your multilevel BOM on one screen.

The following are examples of situations in which the where-used list provides information:

  • Calculating the requirements for a particular material
  • Identifying the products that are affected by a change to an individual part
  • Identifying the assemblies that will be produced late. For example, because of a delay in the delivery of a raw material
  • Calculating the cost effects on a product if raw material costs change

Explode Bills of Material

With the Explode Bills of Materials app you are able to execute a multilevel BOM explosion.

With this app, you are able to execute a multilevel BOM explosion. Inside this app, you can decide, whether you would like to execute a Multilevel Explosion, or Summarized Explosion, expand all levels, or collapse them.

Inside screen settings, you can decide which of the 197 columns should be displayed.

An export to a spreadsheet is also possible.

BOM Comparison

The BOM comparison can be used for single level or multilevel BOMs. Only two BOMs can be compared.

The BOM comparison is useful in the following cases:

  • When several BOMs exist for a material.
  • When BOMs have different uses.
  • When BOMs have different change statuses.

The BOM comparison can be single-level or multilevel, and you can select the fields you need to compare.

Use multilevel BOM reporting
