Lesson Overview
At the conclusion of this lesson, you will be able to prepare and execute the billing process in dialog mode.
Business Example
Print Service Corporation runs a billing process with the technical name BIDA Billing Data and Telecommunication for summarization of data and telecommunication charges into one billing document, because in invoices both are shown as one item, usage dependent charges data and telecommunication. For a customer it is not relevant that they come from different rating and charging systems.
Billing Process Execution

The billing process in contract accounts receivable and payable groups billable items into billing documents.
The billing processes assume the following tasks:
Selection and grouping of billable items into billing documents
Creation of the billing document as the basis for invoicing
The billing processes use the mass processing function in FI-CA to reduce processing time. It is also possible to create billing documents in dialog mode.
You can use reports to analyze raw data and billable items in preparation for further processing.
In SAP Easy Access menu Telecommunications → Contract Account Receivable and Payable → Convergent Invoicing → Billing Documents → Display Billing Worklist.

To monitor billable items, execute transaction FKKBIXBIT_MON (SAP Easy Access menu Financial Accounting (New) → Contract Account Receivable and Payable → Convergent Invoicing → Billing Documents → Display(Transaction FKKINVBILL_DISP). Within the SAP Fiori launchpad use app Display Billable Items for monitoring.
The system displays the items as ALV lists, separated according to their record type, on the Main Items, Payment Data Items, and Tax Items tab pages.
The Restore (Restore Items) push button is only available if you monitor billable items with the status excepted. If you choose this push button, the report restores the selected items. This means that the report places the items in the table for billable items. A dialog box appears prompting you to enter a reason for restoring the item. For the functions except, restore, simulate, and bill, the number of items to be processed can be greater than the number of selected items, as the system considers dependencies among the items.
You can except billable items from billing. The system then moves these items into a separate table, which excludes them from billing. When a billing document is reversed, the system automatically excepts the items. In this case, the system determines the exception reason using the reversal reason that you entered in customizing for contract accounts receivable and payable under Convergent Invoicing → Basic Functions → Billable Items → Billable Item Management → Reversal of Billable Items.

The system can execute billing in dialog mode or automatically for mass billing.
For mass billing, use app Execute Billing or go to the SAP Easy Access menu and choose Financial Accounting (New) → Contract Account Receivable and Payable → Convergent Invoicing → Periodic Processing → Billing → Execute Billing(Transaction FKKBIX_MA).
For billing in dialog mode, use app Execute Billing Business Partner or go to the SAP Easy Access menu and choose Financial Accounting (New) → Contract Account Receivable and Payable → Convergent Invoicing → Billing Documents → Create . Or use transaction FKKBIX_S.
Billing in Dialog offers you the possibility to create simulated billing documents without generating invoicing orders.
The preview option displays a billing document before it is posted to the database.
Creation of Billing Units
If the system processes more than one billable item when billing a contract account, it is often necessary not to process these billable items in one common billing document. Instead, they are grouped according to criteria such as common currency or common billing period, and a separate billing document is created for this group. Billing in contract accounts receivable and payable determines this issue by creating billing units.
A billing unit groups all billable items together that are processed together in a billing run, and for which the system creates a common billing document.
The creation of billing items can be performed automatically using the rules stored for grouping control for the billing process. You can also control the creation of billing units manually in billing dialog processing.
Process
The automatic creation of billing items is performed in the following steps:
- Step 1
The system groups all the selected billable items together that share the following properties:
Contract account
Business partner
Subprocess
The system does not add billable items to the billing unit that do not correspond in respect to one of these fields.
- Step 2
The system determines the grouping variant. You determine which grouping variant is to be used depending on the billing process, subprocess, and (optionally) invoicing category in customizing for contract accounts receivable and payable in the activity Define Billing Processes. If no grouping variant can be determined for the billing process, the system processes all billable items selected for the billing process and contract account in a common billing document.
Grouping variants are discussed later in one of the following lessons.
The result of the billing run is the billing document.
SAP Easy Access Menu: Accounting → Financial Accounting → Contract Accounts Receivable and Payable → Billing → Display → Billing Document
Select Contract Account: CABOVI02.

A billing document consists of the following elements:
Billing document header
Billing document items
Reversal data for the billing document
Optional elements are:
Payment data items
Additional items
Source items
Tax items
To display billing documents, use app Display Billing Documents or go to the SAP Easy Access menu and choose Financial Accounting (New) → Contract Account Receivable and Payable → Convergent Invoicing → Billing Documents → Display (transaction FKKINVBILL_DISP).
