One of the most significant features of a Profitability and Costing model is its ability to integrate operational costs into a model in a way that enables it to generate an analysis of costs using its built-in calculation engine.
The dimensions involved in a Cost Analysis model are loosely demonstrated in the following diagram, which shows how the calculation engine operates for a particular combination of <Version> and <Period>. Starting from the base costs, <Line Items> and <Services>, and resources in each <Responsibility Center>, it can project these costs across the Activites performed in each <Responsibility Center> and further project them across <Cost Objects> using Resource Driver Splits and Activity Drivers.

<Cost
Objects> are combinations of items across your
<Cost
Objects> dimensions. This provides excellent granularity for
determination of individual costs, which is enhanced by the ability to
summarize results through the group features implicit in the
<Cost
Objects> and Attributes hierarchies.
The steps involved in setting up a basic Cost Analysis model are:
Setting up an <Activities> Costing model can be considered separately from a <Cost Objects> Costing model.
