Lesson Overview
Consumption item management is similar to billable item management in its approach.
Understand how a consumption item class is created and what customizing is necessary in order to trigger rating for consumption items.
Business Example
Consumption items are stored in consumption item class CVOI. Consumption item class CVOI stores voice calls for rating in CI. Rating process RVOI is defined to select consumption items from consumption item class CVOI.
Customizing - Data Storage and Rating in CI
Rating units are created along provider contracts. That means consumption items from different provider contracts are rated separately.

Business Scenario with SAP Convergent Charging:
A consumption item class in SAP CI corresponds to a chargeable item class in SAP CC. This means that the name of the class, the fields and the field names must be the same.
Use the same consumption item class, if the fields for different consumption item types are not too different. Create a new consumption item class if there are too many differences between consumption item class structure.
Create a new consumption item class, if rating is done in different rating systems.
Hint
Consumption item classes are cross-client.It is recommended that you use a given consumption item class only in one client. This approach means that you can avoid dependencies between different clients, especially as regards the configuration of data storage and deletion time limits.


Interface components:
Basic data for consumption items (see next page)
Consumption item label includes access key (user ID, service ID) for integration with CC
External provider contract reference – field for provider contract reference
SAP Convergent Charging activates interface to convergent charging
From a technical perspective, an interface component consists of the documentation of the component, the selection of required fields, the specification of dependent/prerequisite interface components, along with checks, derivations and assignments of fields.


Basic Elements of Rating
The following documentation gives you an overview of the concepts and parameters that control data storage and rating of consumption items during rating.
In addition to the most important concepts, the following sections also explain the usage of the individual parameters, the possibilities available when using them are explained on the basis of examples, and the settings in customizing are discussed.

For rating of consumption items in CI, a function module which does the simple rating minute and price/minutes is assigned to rating group.
The rating group defines in which steps rating is done.
Consumption item class CVOI is assigned to rating group RVOI. In the next exercise, some more consumption item classes are assigned to the same rating group.
For more complex rating rules, rating of consumption items is done in SAP Convergent Charging. It is also possible to do rating in other rating systems.
In case of integration with SAP Convergent Charging, billable items are created in SAP Convergent Charging and sent to SAP Convergent Invoicing.

Group into different groups along different provider contracts and consumption dates (without timestamp).
Grouping Variants are introduced in the following:
To build rating units. A rating unit consists of all consumption items that are rated together.
To propose which consumption items should be aggregated (used in business example).
Aggregation variants are introduced to define the field content of the aggregated consumption items.
