Bills of material and routings make up the quantity structure of a product. The product costing determines material and production costs of the product based on this quantity structure.

The definition of the quantity structure of an AFS material (product) enables you to define grid and category-dependent specifications. These specifications can also be cost-relevant.

For the definition of the bills of material of AFS materials, the following costing-relevant functions are available:

• If you use AFS materials in the BOM as components whose grid values are different than those of the finished product,
  determine for each grid value of the finished product which grid value of the component material should be available for production and in which quantity.

• If you use AFS materials in the BOM as components whose grid values are identical to those of the finished product,
  specify for each component material a standard input quantity. If necessary, enter variances from the standard input quantity for each grid value of the finished product or enter the input quantity zero.

• Depending on the produced category of the finished product, you can usually specify (for all grid values) whether or not certain components should take part in the BOM explosion.

The production operations are often different depending on the category produced. You can therefore create several alternative routings for one material with the AFS system.

In the routing header of an AFS material you can specify whether or not the routing alternative should be used in the production of a certain category.
