Beispiel: Example: Creating a Costing Model for Projects
Starting Point
Your company frequently handles projects in which supply ditches are dug, pipes laid, and the ditches filled in again. These projects vary according to the size of the ditch and the diameter of the pipe.
Prerequisites
For this example, the following data must be available in the system in controlling area 1000:

) the characteristic group Banks
has been created for you (Banks). You use this group to flag the characteristics that you created.Cost center 4298 (engineering) with activity types 1420 (machine hours) and 1421 (labor hours)
Cost element 420 000 (direct labor costs)

Creating the Costing Model
An overview of the steps needed to create a costing model is provided under Editing Costing Models and Assigning Attributes.
Choose Logistics
Project System
Basic Data
Templates
Models for Easy Cost Planning
. Choose 
on the right-hand side of the screen. Create costing model DITCH_A with the description Ditch
of category A.
Assign characteristics to the model. To do this enter the respective name under Characteristic name
in the table in the bottom right of the screen, and choose Continue
. This way you access the transaction for creating the characteristics. When you have created a characteristic, save it and create the next one.
Create the following characteristics and attributes:
Name | Description | Data Type | No. of Places | Decimal Places | Unit of Measure | Template |
|---|---|---|---|---|---|---|
DITCH LENGTH | Length of ditch | Numeric format | 4 | 1 | M | __,_ |
DITCH WIDTH | Width of ditch | Numeric format | 2 | 1 | M | __,_ |
DITCH DEPTH | Depth of ditch | Numeric format | 2 | 1 | M | __,_ |
DURATION | No. of required days | Numeric format | 2 | 0 | Days | |
FLAT RATE | Travel costs flat rate | Currency format | 4 | EUR | ||
PIPE | Supply pipe | Character format | 20 |
You can only define and change the attributes when you maintain the characteristics. To change a characteristic, choose 
in the table.
For all characteristics, choose Characteristic Group
Banks.
Set the indicator Entry required
for all characteristics. If you also want to use the model for projects that do not involve the laying of a pipe, do not set the indicator for the characteristic PIPE
. The cost planner should not select a value and no costs will be calculated.
Define the following values
for the characteristic PIPE
:
Characteristic value | Description |
|---|---|
1 | Diameter 10 cm |
2 | Diameter 20 cm |
For more information, see Creating and Assigning Characteristics.
Click on the node: Define the derivation rules (template)
. Select WBS element under Reference object
. Enter the following lines in the template:
In the Type
column, select the item category for the template using the input help. Use the input help also in the Object
column and call the formula editor in the Quantity
and Activation
columns by double-clicking in the cell, if characteristics are being used.
Type | Description | Object | Quantity | Activation | Price |
|---|---|---|---|---|---|
Cost center/activity type | Labor costs for the digging of the ditch | 4298 / 1421 | DITCH LENGTH x DITCH WIDTH x DITCH DEPTH / 10 | ||
Cost center/activity type | Machine costs for the digging of the ditch | 4298 / 1420 | DITCH LENGTH x DITCH WIDTH x DITCH DEPTH / 10 | ||
Material | Supply pipe | 0001 / PIPE-10 | DITCH LENGTH | PIPE = ‘Diameter 10 cm‘ | |
Material | Supply pipe | 0001 / PIPE-20 | DITCH LENGTH | PIPE = ‘Diameter 20 cm‘ | |
Cost center/activity type | Labor costs for the laying of the pipe | 4298 / 1421 | DITCH LENGTH / 5 | PIPE = ‘Diameter 10 cm‘ OR PIPE = ‘Diameter 20 cm‘ | |
Cost center/activity type | Labor costs for filling in of the ditch | 4298 / 1421 | DITCH LENGTH x DITCH WIDTH x (DITCH DEPTH -0.1) / 10 | PIPE = ‘Diameter 10 cm‘ | |
Cost center/activity type | Machine costs for filling in of the ditch | 4298 / 1420 | DITCH LENGTH x DITCH WIDTH x (DITCH DEPTH -0.1) / 10 | PIPE = ‘Diameter 10 cm‘ | |
Cost center/activity type | Labor costs for filling in of the ditch | 4298 / 1421 | DITCH LENGTH x DITCH WIDTH x (DITCH DEPTH -0.2) / 10 | PIPE = ‘Diameter 20 cm‘ | |
Cost center/activity type | Machine costs for filling in of the ditch | 4298 / 1420 | DITCH LENGTH x DITCH WIDTH x (DITCH DEPTH -0.2) / 10 | PIPE = ‘Diameter 20 cm‘ | |
Variable item | Travel costs | 420000 / H | DURATION | FLAT RATE |

Result
You can now use the costing model to plan the costs for WBS elements. Assume that you have a project to develop a residential area and one of the WBS elements for the project is Lay Supply Pipe in Tony Benn Street. You can call up Easy Cost Planning for the project, select the WBS element node, and then choose planning form DITCH_A. After you have entered the data for Tony Benn Street and chosen Confirm
, the costing results are displayed in the Costing Structure
screen area. For more information, see Using Easy Cost Planning and Easy Cost Planning in the Project System.
