Manual billings (such as corrections to bills) are automatically included in invoicing. You do not need to make additional settings in Customizing.
Paid budget billing amounts are automatically included and posted in statistical budget billing. In the debit entry procedure, the budget billing amounts remain and are not reposted.
During the invoicing process, FI-CA items can be processed using settlement control. To allow this, you have to configure settlement control accordingly in Customizing. For example, payments on account could be settled against receivables from the annual consumption billing. Cash security deposits should also be settled in a final billing.
You can also use settlement control to settle remaining credit against the first or next budget billing amount.
The due dates of outstanding receivables are not grouped with the first or next budget billing amount as there is nothing to settle (both are receivables). For this reason, the due dates are grouped in a separate Customizing table in invoicing.
Sub-items (open items in the contract account) can be displayed on the bill. However, you must note that these items are not part of the contract accounting document, and still have separate due dates. Therefore, you should check if you really want to include the items in the account balance.

You can define the following for each settlement type and category:
Account maintenance: you must activate account maintenance in invoicing if you want to use settlement control, such as settlement with the first budget billing amount, settlement of cash security deposits in the final billing, settlement of payments on account.
