Integrating External Billing Systems

Purpose

For exchanging data between Contract Accounts Receivable and Payable (FI-CA) and an external (billing) system, in SAP Exchange Infrastructure (XI), SAP provides various different message interfaces.

Notes on Implementation

Make sure that the process integration content of the software component FI-CA has been imported to your integration repository. The process integration content for Contract Accounts Receivable and Payable is on SAP Service Marketplace. Here the content is displayed as a patch under the respective industry solution (for example, SAP IS-T).

Features

You configure the link between the message interfaces of the software component FI-CA and external systems in the Integration Directory of your Integration Server (see Basics ).

For more information about the interfaces and their use, see the following section. You can use the following message interfaces in Contract Accounts Receivable and Payable for the connection to external (billing) systems:
