You can define keys for Partner Settlement Categories in Customizing to suit your requirements: Financial Accounting → Contract Accounts Receivable and Payable → Convergent Invoicing → Partner Settlement → Define Categories of Transactions to Be Billed.
Additionally one or more Reasons for Partner Settlement have to be assigned to each partner settlement category.
These reasons are created in Customizing, where also a function module is assigned to each reason: Financial Accounting → Contract Accounts Receivable and Payable → Convergent Invoicing → Partner Settlement → Define Reasons for Partner Settlement.
The function module decides if a partner CIT is to be created and how the main characteristics of this item are populated (Determine the "Access"): In order to rate a partner CIT SAP Convergent Charging has to determine the partner agreement the consumption items belongs to. Therefore a consumer ID (or partner ID or access-user ID) and a service ID have to be set in the partner CIT.This procedure is technically equivalent to the rating and charging of end customers where for instance the telephone number of the caller is used as the consumer ID and the service ID of the consumption item is a category such as SMS or VOICE.
Once categories and reasons are defined, you assign them in an assignment table. With this assignment, one or more reasons can be considered for one Partner Settlement Category. This means that from one customer service usage event one or more different partner shares can be split off.
Events for Consumption Item Creation
It is also possible to populate additional fields in the partner consumption item as needed. For instance, many price models require that the amount charged to the end customer has to be adopted as information in the Consumption Item for Partner Settlement. You can adopt further attributes in the Consumption Item for Partner Settlement according to your individual requirements using the new event 0561.
It can be the case that you use your own program logic for generating consumption items for partner settlement and are not able to use the described examples for your processes. In that case, you can implement a customer-specific function module that you can register for the new event 0560. In that case, using the Partner Settlement Category as the starting point is optional.
