What Are Target Costs in CostCenter Accounting and WhyShould You Calculate Them?
by Janet Salmon, Solution Manager, SAP AG
March 15, 2004
SAPexperts/FinancialsMany reports that monitor cost center performance areincomplete because they account for the planned outputrather than the actual output of the cost center. The author demonstrates how to use adjusted costs called targetcosts. Calculating target costs will provide you with areport that more accurately reflects the performance of your cost centers.
Ask most people to define Cost Center Accounting (CO-OM-
CCA) and they will tell you that it is the process of assigningexpenses to cost centers and monitoring these figures over
time. Ask them how they monitor cost center performance and
these people will tell you that they compare the actual costs
with the planned costs for the period and analyze the variance.
They typically work with reports like the one shown in Figur e 1,
with a line-by-line explanation of the over/under absorption on
the cost center. (For information on reports in Business
Information Warehouse [BW], see the sidebar, "Analyzing
Target Costs in Business Information Warehouse.")

However, while everyone is familiar with this sort of report, it
has its limitations. To understand how their cost centers are
performing, some companies go a step further and adjust their
planned costs to reflect the actual output of the cost center.
They then compare these adjusted costs — SAP calls them
target costs — with their actual costs to calculate variances.
This gives them a more accurate picture of how efficiently their
cost centers have been working, because it accounts for
variations in cost center output. Using five cost centers in a
fictitious manufacturing company, I will show you why
companies use target costs instead of planned costs to judge
their cost centers' performance and what impact this business
requirement has on their planning process.

Target Costs
In a nutshell, target costs reflect the output rate of the cost
center. If the cost center's output is higher than planned, then it
probably spent more than planned. If the cost center's output is
lower than planned, then it probably incurred fewer costs.
Some costs — the fixed costs — are unaffected by the change
in output. The term "target costs" is best understood by lookingat the German word "Sollkosten." These are the costs that
should have ("Soll") been incurred to achieve a given output.
Do not be misled by the fact that the term sounds like "target
costing" — working back from a market price (the target) to
arrive at the product costs. Calculating target costs is all about
looking backward at what was planned and adjusting this plan
to reflect the actual output. This brings us to the crux of the
matter. Calculating target costs has a major impact on
planning. You need to plan:
What the cost center output is: in SAP terms, the activity
types to be performed and the quantities of that activity(output) to be provided
What the cost center spends to perform this activity:SAP differentiates here between activity- dependentcosts and activity-independent costs
How the output of this cost center is to be used: howmuch of each activity flows to other cost centers,business processes, and orders in the course of theplanning period
This is a much more detailed form of cost center planning than
many organizations currently perform, but it provides a way to
establish the targets for the cost center and to measurewhether these targets were achieved. This form of planning
also presupposes that the activity flow is reconciled — supply
reflects demand — and that the flow of activities will be valued
with a price that is calculated by dividing the planned costs
either by the planned activity or (more rarely) the planned
capacity for the cost center.
Activity Types
The activity type describes the output of the cost center. In
manu- facturing companies, it is standard practice to calculatethe number of machine hours or labor hours expected for the
period based on the quantities in the production plan and the
number of maintenance hours, quality control hours, and so
on, that will be required to provide these machine hours. It is
becoming increasingly common to find Activity- Based Costing
(ABC) methodologies being used by service companies to
determine the number of labor hours required to provide
certain services. What matters is that all cost center allocations

should use activity types. If you use assessment cycles to clear
some of the cost centers at period close, you will have no
activity quantities and consequently no target costs for these
cost centers.
In my example, the service cost center's energy, quality, and
repairs provide the following activity types to two production
cost centers: kilowatt hours, quality hours, and repair hours.
The production cost centers provide machine hours to the
production orders processed by them.
Activity-Dependent and -IndependentCosts
To calculate target costs properly, you need to plan the activity
output (number of hours) for your cost center and to distinguish
in your plan between activity-dependent and activity-
independent costs. The activity-independent — or fixed —
costs are expenses like salaries and facilities that are incurredeven if the cost center is idle. The activity-dependent costs are
expenses like energy, direct labor, and external processing,
that change with respect to the output of the cost center. These
costs can either be totally variable (as might be the case for
external processing) or a mixture of fixed and variable costs
(as might be the case for direct labor costs).
In Figure 2, you can see that the fixed costs for the cost center
quality control are Salaries and Office & Building, the costs for
External procurement vary with the number of quality hours
worked, and that Direct labor costs is a mixture of fixed and
variable costs. To plan activity output and/or capacity, choose
Accounting>Controlling> Cost Center
Accounting>Planning> Activity Output/Prices>Change.
Choose a planning layout that allows you to enter the activity
quantity and/ or capacity for each activity type on the cost
center. For more information on planning layouts, see the
sidebar, "Setting up Planning Layouts." To plan the costs to
provide this output, choose Accounting> Controlling>Cost
Center Accounting> Planning>Cost and Activity
Inputs>Change. Choose a planning layout that allows you to
enter first the fixed costs on the cost centers by cost element
and then the activity-dependent costs on the cost centers by
cost element and activity type.

Activity Usage
The information planned so far would be sufficient to calculate
an activity price and target costs for the quality control cost
center in isolation. However, you have not yet planned which
cost centers will use quality control hours. You also need to
plan the activity allocation for quality control — 1,200 hours to
PC production and 600 hours to chip production. Figure 2
shows the planned costs (activity-dependent and activity-

independent) for a quality control cost center, the planned
output (1,500 hours), and the planned usage of this output in
chip production and PC production.
To plan activity input, choose Accounting>Controlling>Cost
Center Accounting>Planning>Cost and Activity
Inputs>Change. Choose a planning layout that allows you to
enter both the sender cost centers and activity types (quality in
my example) and the receiver cost centers and activity types
(chip and PC production in my example).
Plan Reconciliation
If you look closely at Figure 2, you see that the activity usage
planned — 600 hours to chip production and 1,200 hours to
PC production — is higher than the output planned for the
quality cost center — 1,500 hours. The plan reconciliation
function takes account of this discrepancy and adjusts the
planned cost center output from 1,500 to 1,800 hours to reflect
the demand from the production cost centers. It also adjusts
the activity-dependent costs accordingly. Thus, the variable
costs for External procurement are now EUR 108,000
instead of EUR 90,000 and the variable costs for direct labor
are now EUR 36,000 instead of EUR 30,000. This is illustrated
in Figure 3.

Activity Prices and Capacity
The price indicator for the activity type determines whether the
activity price for a cost center is based on the planned quantity
or the capacity. Price indicator 1 means that the activity price is
calculated by dividing the costs by the planned activity. Price

indicator 2 means that the activity price is calculated by
dividing the costs by the planned capacity.
The activity price is used to assign costs from the quality
control cost center to the production cost centers based on the
quantities confirmed. This price is analyzed when variances
are calculated. If the cost center has not operated at the rate
planned, the price includes fixed costs that are too high or low
and these appear as a fixed-cost variance for the quality cost
center. If the activity price is changed — for example, by using
a manual correction — variance analysis reveals an output
price variance on the quality control cost center and input price
variances on the production cost centers.
Some companies do not calculate their activity prices in R/3 at
all, but instead calculate them manually and upload them from
a spreadsheet. In this case, the price indicator 3 is used. This
does not affect your ability to calculate target costs and
variances.
Calculating Target Costs
Let's assume now that actual costs have been incurred and
activities have been posted to production. If the quality control
cost center had provided 150 hours of activity in January as
planned, the report you saw in Figure 1 would provide ample
explanation. However, if the operating rate for the cost center
is different, the target/actual comparison provides a better
reflection of the business for the period in question, because it
adjusts the planned costs to reflect the fact that 160 hours of
activity were actually provided in January. The variableplanned costs is adjusted to reflect the higher amount of
activity.
If you compare Figure 1 to Figure 4, you can see that the
totals have changed. In Figure 1 the total planned costs were
EUR 29,000 and in Figure 4 the total target costs are EUR
29,800. All cost elements containing activity-dependent costs
— in this case, external procurement and direct labor — have
been affected by switching from planned costs to target costs.
Thus, the planned/actual comparison shows a variance of EUR
3,000 for External procurement and no variance for Direct
labor costs, whereas the target/actual comparison shows a
variance of EUR 3,600 for External procurement and EUR
200 for Direct labor costs. Only the activity-independent costs
— Salaries and Office & Building — remain the same.

The control costs are the actual costs assigned to thecost center for the period (in Product Cost Controllingthey have been cleansed of any scrap or work inprocess, but in CO-OM-CCA they are all input costs).
The target costs are the planned costs adjusted toreflect the operating rate (in this example, 106.67percent).
The actual costs allocated are the costs assigned fromrepairs to production using the planned activity price for the cost center.
SAP distinguishes between input variances (those resulting
from changes in the costs coming in to the cost center) and
output variances (those resulting from changes to the output of

the cost center or the activity price).
The input variances are:
Input price variances occur as a result of changes to theactivity prices for other cost centers or material pricechanges
Input quantity variances occur as a result of using adifferent quantity of activity from other cost centers
Resource-usage variances occur if an activity is used from another cost center than wasoriginally planned
Remaining variances is a catch-all for any unassignedvariances
The output variances are:
Output price variances occur if the activity price ischanged for any reason
Fixed cost variances occur if the operating rate changesresult in an over- or undercharging for the fixed costs inthe activity price. In my example, the production costcenters were overcharged for the fixed part of theactivity price (salaries and building costs).
Remaining variances is a catch-all for any unassignedvariances
Managing Cost Center Performance
Companies that use target costs extensively judge their cost
center managers not on their ability to stay within a budget, but
by their ability not to exceed their target costs. They expend a
great deal of energy planning activity inputs and outputs
because they believe it reflects the business they plan to do in
the next planning time frame. They know that the business
environment will change, but they use the target costs to reflect
the fact that their cost center had more or less work than they
had anticipated at the time of planning.
Companies running ABC can use the same functions to
analyze both cost center costs and process costs. In this case,
as well as planning the outputs of their cost centers, these
companies plan the process outputs based on the quantities of
activity required to meet their sales plan and then adjust the
planned process costs to reflect the actual process output for the period. The notion of detailed output planning and the
"flexing" of the planned costs to reflect actual output is central
to SAP's approach to CO-OM-CCA and ABC. Unfortunately,
the significance of the target costs often gets lost in translation,
meaning that companies miss out on an effective method of
managing cost center performance.

Warehouse
The reports shown in this article have been accessed directly
from SAP's R/3. Similar reports are available within Business
Information Warehouse (BW).
To build reports like those shown in Figures 1 and 4, you
should use InfoCube 0CCA_C11 (CO-OM-CCA: costs and
allocations). This InfoCube contains the totals on the cost
center. To provide the base data for Figure 1, use InfoSource
0CO_OM_CCA_9 for the actual costs (value type 010) and
InfoSource 0CO_OM_CCA_1 for the planned costs (value
type 020). To provide the base data for Figure 4, create an
additional InfoPackage for InfoSource 0CO_OM_CCA_1 and
select the target costs (value type 030). Schedule this
package to load monthly, when the calculations in R/3 are
complete.
To build reports like those shown in Figures 2 and 3, use
InfoSource 0CO_OM_CCA_2 to extract the costs per activity
type to InfoCube 0CCA_C02 (CO-OM- CCA: Costs andallocations by activity type) and InfoSource
0CO_OM_CCA_3 to extract the activity quantities and
capacity to InfoCube 0CCA_C04 (CO-OM-CCA: activity
quantities and prices).
To build reports like that shown in Figure 5, you should also
use InfoCube 0CCA_C11. If you intend to build your own
queries, you should activate the restricted key figures for this
InfoCube to save you from having to define key figures for
each of the variance categories I mentioned.
Setting up Planning Layouts
The screens in which you enter data during planning are
configurable, so you may find that suitable planning
layouts do not exist in your productive system if your
organization is not doing the sort of detailed planning that I
have described. To set up suitable planning layouts,
choose the IMG menu path Planning>Manual
Planning>User-Defined Planning Layouts>Create
Planning Layouts for Cost Element Planning or Create
Planning Layouts for Activity Type Planning. These
transactions take you to Report Painter, where you can
position the fields you need in a planning layout that meets
your planners' needs. In my example, I entered the activity
quantities and capacities in layout 1-201 (activity
types/prices), the costs to provide the output in layout 1-
101 (cost elements) and the activity input in layout 1-102
(activity input) — all of which are standard settings. At a
customer site I would probably copy layout 1-102 and
create separate layouts for activity-dependent and activity-
