 Auxiliary Cost Component Structure with Primary Cost Component Split (Material Cost+ Processing Cost) in Product Cost Estimate- Part 1

The blog written titled “https://blogs.sap.com/2015/09/11/primary-cost-component-split-for-cost-estimation/” details some of the features of primary cost split and also espouses his views on the usability of the functionality.

And explained the “Understanding of Cost Component Structure” by Mr Hrusikesh Dalai “https://blogs.sap.com/2013/11/25/basics-of-standard-costing-understanding-the-cost-component-structu...

I would like to supplement his thoughts with certain other insights as well. But before that, a few generic impressions…


Primary Cost component split for (Material + Activity (processing) Cost)

First I would like to add the feature of Material cost component split as “Raw Material Costing” for no BOMs or routings for raw materials in the system. You can, however,

  • Use these functions to create a cost estimate for raw materials enables you to include delivery costs.

  • Access the purchasing data (MM_PUR), in order to include delivery costs such as freight charges and insurance costs

  • Transfer structure for the “Primary cost component split” to Main Cost component

  • Splitting the Main CCS to Aux CCS (Material Cost = Material Cost + Delivery Cost), Main activities cost in to various components with Primary Cost component split.

The primary cost component split is an alternative way of showing the cost of goods manufactured of a product. This cost component split assigns the primary cost elements for the cost center or process to the cost components, which enables you to see the composition of the price for the activity type or the costs for the process.

The primary costs from Overhead Cost Controlling can either be transferred directly into the primary cost component split of the product or assigned to other cost components. In this way, you can explode the costs for specific internal activities partly by their primary costs, and combine them partly as secondary costs.

Benefits/Features of Cost Component Split – Auxiliary CCS

  • This can exist in addition to the main cost component split, and is not used in the standard cost estimate. It can be used for analysis purposes, in that it can be displayed with the cost estimate and passed on to Profitability Analysis.

  • Synchronizing the Main Cost Component structure components like, Material Cost + Activities in various levels for better analysis and reporting purpose.

  • This CCS analysis can explore in Material Ledger price analysis with different Cost Component structures

  • Actual values will flow to COPA to the respective values fields’ mapped w.r.f to Auxiliary CCS.

Main Cost Component Structure


  1. Auxiliary Cost Component Structure

 In Auxiliary cost component structure you can differentiate the “Cost component in detail w.r.f to Main CCS” whereas I took the example of Freight Cost component as created in first slight “Origin Groups”

Note: Ensure that do not assign any 43 category cost elements in the above step. Assign only all primary cost elements.

Assign the Material Consumption GL Accounts to cost components additionally with “Origin Groups” this enables to display the Raw Material Cost + Delivery (Freight) component in Auxiliary CCS.

The below detail explained the Main and Auxiliary CCS- Assignment of Primary Cost Elements with Origin Group

 Transfer Structure

Controls the transfer of costs from the cost components of one cost component structure into the cost components of another cost component structure.

The transfer structure determines how the costs of the sending cost component split (such as the primary cost component split of an internal activity) are transferred to the receiving cost component split.

Through the transfer structure, a single cost component of the receiving cost component split can be assigned to every cost component of the sending cost component split.

If the cost component structure of the primary cost component split for the cost center activity prices is not the same as the cost component structure of the primary cost component split for the products, you can use the transfer structure to specify how the cost component split of an internal activity or process for a material cost estimate is transferred into the cost component splits of the material costed.

In contrast to the switching structure in Cost Center Accounting, which reassigns cost components within a single cost component structure, the transfer structure assigns cost components between two different cost component structures.

I summarized the splitting structure process steps in this explanation because one of our SAP former member/supporter explained in very excellent way on this context, please refer the below link


  1. Plan Activity Calculation- KSPI

The below table content the plan activity calculation for all activities (Fixed/Variable) derived the same result as above in KSBT

The below is Activity cost calculation explanation for (Power/Energy) as per cost planned and rate calculated above to Main & Auxiliary Cos Component Structure.

In this document in tried to explain the utilization of Auxiliary Cost Component structure with “Primary Cost Component Split” for Material Cost and Activities. In my next series of document I will explore for this scenario to Actual posting considering the S/4 HANA COML Actual Costing + COPA (Account based + Costing based) reporting.

Hi Mansoor ,

Informative blog,

I have doubt in CCS.

You have defined 800000- Energy and 800001 - Labor  in Primary Cost Split(F0).The same not been defined in Auxiliary split.

During Order settlement I think this is will be error. Have u checked the order settlement(KO88).Will You able to Check and confirm.

Dear mansoor.khan4

I have one question why we put in OKEQ the Cost Component Struct Auxiliar?

If i put the principal Cost Component Structure in OKEQ what will be the impact and the changes i will see?

Hi Leonardo

The primary objective of Auxiliary CCS is to split from Main CCS (Secondary CEs) to Auxiliary CCS (Primary CEs).

The major impact analysis with this concept is to minimize the Cost Component Structure items (Ex. for labor) splitting from Main CCs to Auxiliary CCs.

The primary feature is to analyze in Product Cost Estimate >> with Main CCs as (Labor) summary & Break-up/Split from Auxiliary (Direct/Contract) which is explained in detail in blog...


Example for One Cost Component item
Main CCS Aux CCS

Direct Labor 6****10 Direct Labor 1
Activity Cost Component CE-Secondary 6****11 Direct Labor 2
2000 Labor 8**** Labor Contract Labor 6****12 Contract Labour-1
6****13 Contract Labour-2
Cost Element Planning via KP06
Activity Name
2000 Labor 6****10
2000 Labor 6****12

Hello,dear ;
if I do not use  auxiliary cost component structure ,only use the main cost component structure,can I use the function of Primary Cost component split?  

In the main cost component structure,realize the aim to Detailed cost component no need the auxiliary。This way is also OK?

Look forward to your comments, thanks
