Definition
A user-defined grouping of costs that divides the costs of the materials into
cost components and reflects all the production levels.The amount of cost components is the same for each material, thus providing a valuable comparison of the cost estimates. The cost component split provides the basis for an analysis of the value added at each stage of the production process.
Use
The cost component split enables you to do the following:
To this end, cost component views are created that display, for instance, cost components relating to stock valuation, or the cost of goods sold.
Costing enables you to analyze the value added within a multilevel production structure. You break down the costs for each material with a BOM according to the upper level and lower level.
You display the cost component split by choosing Costs ® Display cost components. You can break down the costs for each material according to the upper level and lower level. You can make this setting by choosing Settings ® Display variant ® Current… ® Characteristics. You can create your own report using a wide range of selection parameters.
If you display the costs for the
In both cases, the costs are broken down into
cost components. The total costs for the upper level and the lower level equals the total costs for the production level concerned. When the costs are broken down into cost components, the origin of the costs, such as material costs or fixed and variable production costs, remains at each manufacturing level. At each manufacturing level, the cost component split separates the value added of that level from the costs of the lower level.
Furthermore, the cost components can be viewed in various forms, as in the cost of goods sold or cost components relating to stock valuation. You can also specify that the costs are to be updated as an itemization.
You can display the costs as a
cost component split for the cost of goods manufactured, and/or a primary cost component split. 
The
update of the standard price in the material master is carried out with the upper level.An
itemization is created for the leading cost component split only.When you save a material cost estimate or a costing run, the system automatically updates a cost component split for every material that was costed.

This dialog box is suppressed if the Defaults can be changed by user indicator was not set in the costing variant in Customizing for Product Cost Planning. In this case, the system automatically saves the costing results that were flagged to be saved in the costing variant.
You can find further information about saving the costing results under
Saving the Costing Results.
If you want to generate a cost component split for raw materials and purchased parts, you can create additive cost components for these costs for each material. You can then group these cost components in an external procurement cost component structure that contains only such costs. You can find further information under
Additive Costs. For more information about costing results, see the R/3 Library in the Product Cost Controlling Information System under
Cost Components.
