If you are using one of the following industry components, you can transfer billing documents from Sales and Distribution (SD) to Contract Accounts Receivable and Payable (FI-CA) (instead of to Accounts Receivable (FI-AR)) in an integrated scenario within a client:

(See Integration Between SD and FI-CA in the Same System and Client)

As another alternative, if you are using one of the following industry components, you can run Contract Accounts Receivable and Payable (FI-CA) and Sales and Distribution (SD) in distributed systems, and transfer billing documents from Sales and Distribution (SD) to Contract Accounts Receivable and Payable (FI-CA) using IDoc communication:

(See Integration Between SD and FI-CA in Distributed Systems)

You can optimize the runtime for background processing of the billing due list from Sales and Distribution (SD) by setting the Optimization Active indicator in Customizing for Contract Accounts Receivable and Payable under  Integration Sales and Distribution Make Basic Settings . For more information about how the system achieves this optimization, see the documentation for the indicator.
