Features

When you transfer the billing documents, the SAP system maps the external billing information to the SAP-internal billing information. The result of this mapping is stored as a billing document in the SAP system. When you save this billing document, the SAP system creates an invoicing order.

Transfer of Billing Documents to SAP System

In Invoicing in Contract Accounts Receivable and Payable , the inbound interface for billing documents has the following functions:

  • Transfer data from one or more billing documents from external systems

    The inbound interface can be used synchronously by calling a BAPI using RFC. Alternatively, you can use asynchronous processing with IDocs by means of an ALE interface.

  • Transfer external document data to the corresponding structures and fields of the billing document in FI-CA (referred to in the following as "mapping")

  • Save the billing documents to the database if the consistency checks do not return any errors

    An invoicing order is also created for each billing document. If necessary, you can use customer enhancements (BAdIs) to store additional data in customer-specific tables.

From the invoicing orders, Invoicing in Contract Accounts Receivable and Payable recognizes the billing documents that are new and have not yet been processed. Invoicing creates new invoicing documents based on the billing documents and posts the revenues to FI-CA.
