Lesson Overview
With Enhancement Package 7, convergent invoicing has a lot of new features. Some new features are related to the business-to-business context.
To understand the master data we have a view in the following to B2B customers. All master data structures in the training system were created using the CRM system that is integrated with convergent invoicing.
Business Example
Business customer B2B Sales South has two provider contracts. All provider contract master data is replicated to convergent invoicing.
The provider contract starts at 01/01/2017.
B2B Customer Sales South has done a lot of phone calls, that should be rated in convergent invoicing with a simple tariff of 0.19 euro/minute.
Consumption Items are stored in convergent invoicing that represent voice usage between 03/01/2017 and 04/01/2017.
Billing and invoicing should be done separately for each provider contract. Customer B2B Sales South gets a list of daily usage, therefore, one billable item per day is enough.
For example on 03/01/2017 customer B2B Sales South calls 3 times. Tthe system creates only one billable Item per consumption day by adding all durations of the day into one consumption item.
Convergent Invoicing

Referring to the example from unit 1 and the lesson, Introduction to Billing for High Volume Industries.
The network element produces a consumption data record (CDR) that includes technical data such as user ID (phone number of caller), service ID, consumption date, number called, start date of consumption, end date of consumption and duration.
With the new feature data storage in convergent invoicing, the process can be started with storage of consumption items.
Example of a CDR before acquisition and chargin is #ZZ_TOTAL_DURAT; ZZ_CALLING_PARTY; ZZ_CALLED_PARTY; ZZ_START_DATE; ZZ_END_DATE; Service Identifier; User Identifier;
Consumption date: 0;017011;0177;01/06/2016 12:50:00;01/06/2016 12:55:00; VOI; 017011; 01/06/2016 12:50:00
Example of consumption item:
Consumption item class, consumption item type, consumption date, Rating_From, status, BP, provider contract, contract account, consumer ID, service identifier.
Consumption Items

Consumption items are created when a customer consumes a service. Consumption items contain source information about this service. Rated consumption items lead to the creation of billable items.
The consumption item key consists of the ID type and the ID of the consumption item. Together with the ID type, the ID of the consumption item uniquely identifies a consumption item.
The ID type describes the business significance of the consumption item from the rating viewpoint as well as from an external system viewpoint. It also defines rules for how the consumption item ID is interpreted in follow-on processes.
The consumption item class determines the technical characteristics of consumption items. The concept is very similar to the concept of billable item classes.
The various statuses of consumption items are reflected on a technical level using different database tables. There is at least one database table for each status and consumption item class.
There is a separate database table for each month for the status Rated. From convergent invoicing, you can subject unrated consumption items to rating. The system accesses rated items during re-rating to rate the source information again.
Hint
The Abbreviation CIT is in convergent charging used for charged item.

Business Cases for Data Storage of Consumption Items:
Rated consumption Items and billable Items can be linked together, and the consumption source is linked to the price that has to be paid.
Show base of rating on customer invoice: keep all invoice relevant data in one system for consistency purpose.
One more hierarchy level is available with referencing Consumption Items that are the source for billable items.
One more option for aggregation is possible.
Structured Consumption Item information on the invoice.
Correction of consumption items in Convergent Invoicing Correction Workbench.
Manual capturing of consumption in Convergent Invoicing.
Aggregation of Consumption Items before Rating for reduction of Billable Item Volume.
