This Wiki page will demonstrate how to create costing model for Easy Cost Planning and carry out Cost planning using ECP.


The Easy Cost Planning tool enables you to plan costs at WBS level, based on quantities and characteristics. ECP can also be used for Internal Orders & Appropriation Requests.

You use it to create quantity structures (possibly temporary) for the cost calculation, starting from the project structure. The system valuates your entries using the prices and rates defined in the system, then distributes the costs in line with the basic dates for the respective WBS elements.

You can make best use of this tool in the following processes:

●     Project processing concentrating on cost controlling

●     preliminary costing for complex projects

You need to define Costing Model to plan using Easy Cost Planning.  Costing Model becomes a predefined template for costing using quantities.

Following are steps to be followed to create costing model. Create as many characteristics based on number of parameter required for calculating the cost.  For example if the cost of the computer to be calculated based on 1.No. of Computers 2. Hard Disk Capacity 3. Monitor Size 4.Mother Board configuration, then create 4 characteristics.


1.     Create Characteristic (Enter T Code: CT04)


Under value tab define predefined values (these would be available as a drop down)


Similarly define other characteristics 1.MENGE 2.MONITORSIZE 3.MOTHERBOARD

Note: You can create the characteristics directly in Costing Model also.

2. Create Costing Model (Enter T Code:CKCM)

Select Create model as shown below  
Add characteristics created in step1 or else you can create the characteristics directly here.

Click on "Define the derivation rules"


Select reference object as "WBS Element" . Reference Object defines which objects should use this costing model. Since, WBS Element is chosen here, other objects like IO or AR cannot use this Costing model.

Define derivation rule for Number the computers i.e. MENGE Characteristic. Labor charges are calculated based on number of Computers. 

Type: Cost Center/Activity Type

Object: 4205 (Cost Center) / 1421 (Activity Type)

Quantity: MENGE Characteristic 


Define derivation rule for Characteristic "HARD DISK". Based on the Hard Disk Capacity, cost should flow from different material master data. For each Hard disk value, material master data mapping to be done.

Type: Material

Object: 1000(Plant) / DPC1095 (Material)

Quantity: MENGE Characteristic (to multiply the cost based no. of computers)

In activation the relevant value is mentioned to which this derivation rule is applied i.e. here when Hard Disk value is 6 then Material Cost is picked up from Mat:DPC1095).

Similarly define for Hard disk value 9 GB


Similarly define derivation rule for other Characteristics and save the Costing model.


Select the WBS then press SHIFT+F11

Select the Costing Variant and click on "Create Cost Estimates"

Cick on Choose Planning Form and select Costing Model


Input values and click on "Confirm"

Cost is calculated and reflected on left i.e. Costing structure. Overheads are calculated based on Costing Sheet defined in the Costing variant.

    Hi Venkat,

    Thanx for providing steps in ECP.

    Hi, that's great. Are you able to tell me how you can close or delete an existing template to stop users from using it?

    thank you


  3. Nice work Venkat. It was posted in Wiki space Home, now I have moved it to PS Wiki space.

    Is it possible to get discounts?

    If, for instance, the number (MENGE) is > 3 the price on some items is cut down by 10%. Not the number (2 becomes 1,9) but the actual price: The monitor will cost only a mere 358,20 Euro's.

    Thank you
