Activity-based costs

Activity-based costing

After you have declared your driver-dependent cost centers, you have to assign them to activities in your collaboration diagrams, which means that every time the activity is executed, costs are generated. Select an activity within your diagram, be sure to use the simulation property set, and click on 'Activity based costing' (figure 4) for opening an extra window, which will allow you to configure the individual costing.

First, you have to choose the corresponding cost center from the drop-down box to the left (see figure 5). If the drop-down box is empty, be sure that you have declared your cost centers within the same BPI projekt.

Next, you have to choose between three types of costing indicators:

• Flow-dependent means that the value in the column 'cost' will be booked one time per execution of one actitivity.
• Time-dependent means that the amount to be booked depends on the duration of the activity. The value in the column 'cost' will be multiplicated with the individual activity duration.
• Property-dependent means that the value in column cost is multiplacated with the value of the given process variable, which may be individually modified in python scripts.

You only can set a value in the 'Costs'-Column if the selected cost center is declared as driver-dependent. If you select a driver-neutral cost-center here, just the proportional assignment to different processes is influenced here, note the amount of costs itself.
