You use additive costing to add costs manually to a material cost estimate when they cannot be calculated by the system. Examples of such costs are freight charges, insurance costs, stock transfer costs, incomplete or changed BOMs, and routings.
As a rule, costing calculates the costs of a material on the basis of the quantity structure. This type of cost estimate is performed automatically by the system. However, you can also manually enter estimated values for costs that cannot be calculated by the system. This allows you to add costs to a cost estimate that was calculated automatically.
The main prerequisite for including additive costs in an automatic cost estimate is that you carry out both automatic and additive costing on the basis of the same costing variant and costing version.
In addition, you need to carry out or check the following settings in Customizing:
To ensure that the additive costs are included, set the indicator Incl. additive costs for each valuation strategy in the valuation variant in Customizing for Product Cost Planning.
Specify the following through the costing variant in Customizing for Product Cost Planning:
Whether any existing additive costs are to be included in cost estimates that you create with this costing variant
Whether the additive costs are to be included when calculating overhead
Whether the additive costs are to be included when transferring stock to another plant
You create separate cost components in Customizing for Product Cost Planning for those costs which you enter with the additive cost estimate, for example if you want to include the following costs in the cost estimate:
Special direct costs of production
Costs for materials for which no BOM has yet been created
Costs for work sequences for which no routing has yet been created
