Product Costing, part of the Controlling module, is used to value the internal cost of materials and production for profitability and management accounting. Product Costing is a niche skill. Due to costing’s high integration with other modules, many people avoid it due to the complexity. This 5 part blog will seek to simplify Product Costing.

The fourth step in understanding the basics of product costing is the costing run. Costing runs are used to cost mass amounts of materials in a single company code. The costing run allows you to select certain materials, explode their quantity structure, cost, analyze, and mark and release.

Prerequisites:

  • Material Masters (including MRP, Accounting, & Costing views)
  • Quantity Structure (Bill of Materials, Routing or Master Recipe, Production Versions are optional)
  • Purchase Info Records and Condition Types (If desired for costing)
  • Configuration (Cost Component Structure, Costing Variant, Valuation Variant, Costing Sheet if required)
  • CO Master Data (Primary and Secondary Cost Elements, Activity Types, Mixed Costing Ratios & Alternatives if required, Additive Costs if required)

Overview:

During the annual or monthly costing process, materials are costed in a costing run. Transaction CK40N is used to execute costing runs, analyze results, and mark and release costs. The costing run must be created using a costing variant (read more in configuration section), costing version, controlling area, company code, and transfer control. Therefore, a costing run can only be created for one company code at a time. The costing run is also created for a particular date range.

The costing run contains six steps: Selection, Structure Explosion, Costing, Analysis, Marking, and Release. Each step requires you to enter parameters, save, and then execute. The selection parameters are entered which indicates which materials should be costed.  In the structure explosion step, the selected materials are exploded to pick up component materials from BOM’s.

As discussed in the previous blog on Quantity Structure, a bill of materials (BOM) is created for each internally produced material. In the costing step, finished good materials selected from the previous step are costed based on their BOM and routing or master recipe. A routing or master recipe is also created to indicate the processes required for a material. Component materials are also costed based on costing configuration.

You can analyze the costing results using the available reports in the analysis parameters. In the marking step, you open the lock to authorize marking for a company code, costing variant, and period. Once marked, costs appear as planned standard cost estimates in the material master. After executing marking, you release the costing results. Once released, costs are valid for the given date range and appear as current standard cost estimates in the material master.

After executing each step, it is important to review the error log and resolve errors. Once resolving errors in a given step, you must re-execute each step from the beginning to see the effect. If results do not update after executing, you can press the refresh button. You have the option to execute any step in background when processing a large number of materials or if you prefer to execute a step at a given date and time.

Configuration:

Configuration of costing and valuation variants and cost component structure are required to set the strategy for costing materials. The costing variant holds the criteria for costing. Costing variants contain a costing type, which determines the object to be created, and valuation variant. Valuation variants contain parameters for valuation of a cost estimate. In a valuation variant, you can specify the strategy sequence for how costs are selected. For produced materials, the component’s standard cost, moving average price, purchase info record price, or planned prices may be selected. You can also choose a particular plan/actual version and average the plan activity rates for the year or take the current activity rates. The cost component structure is used to indicate which costs should be included, whether to include the variable or total costs, and group costs in logical groupings called cost components.

Relatable Example:

Let’s say we are using Product Costing to value our inventory in a cookie baking shop. This will help us value our cookies (finished good), frosting (semi-finished good), and baking items like eggs, milk, and sugar (raw materials).


Using the costs for each ingredient (Material Master) in our ingredient list (BOM) and the rates for activities in our recipe (Routing or Master Recipe), we can calculate the cost of producing a cookie. In costing our cookies, we will cost the ingredients. Once we are satisfied with our standard cost, we can choose to value our inventory at that cost (release).

Further information:

  • Product Cost Collectors, used in repetitive manufacturing, must be costed in a separate transaction (Individual- KKF6N or Mass- KKF6M).
  • You must re-calculate and release costs to reflect changes in production data like BOMs, Routings or Master Recipes, Production Versions.
  • Note that only the first production version will be used in costing.

In the final blog of this series, I will explain how actual costs are calculated and plan to actual variance analysis.

    Very well done!

    Just one thought — in “Further Information” where you have the note about the first production version, you might also mention procurement alternatives and mixed costing, which allow cost estimates to be based on weighted averages of multiple production versions, or a combination of production versions and different forms of procurement.

    Dear Tanya

    Great job indeed.

    But I want to add one small thing in this is that in the last line of this part you mentioned that “only the first production version will be used in costing.” here one point is already added by Patricia the other point is that we can make default any production version in the material master (Costing1 Tab) to be used for Costing.

    Hi Tanya, Do you have some information about alternatives for costing materials in ATO (Assemble to Order) scenario?

    The final assembly is valuated in stock.

    Very good your post!

    Thanks and regards,

      Thanks for the suggestion Ahmed. The goal of this post was to explain a simple overview of the costing process, and not focus too heavily on costing configuration. There are many other resources that cover costing variants in detail. I am actually writing a book due out this summer on product costing which covers the details of business processes and configuration in SAP. It’s called Practical Guide to SAP CO-PC (Product Costing). If you’re interested, you can read more on my book: TanyaDuncanBlog.com.

      Thanks again for your input!

    hi tanya

    well to begin with im a fresher, but your blogs are so easy to digest,

    Thanks for your valuable information & not to forget the illustration you gave is very easy to absorb.
