Financial Contract Accounting (FI-CA) is part of the SAP Billing and Revenue Innovation Management solution.
The order-to-cash process is covered by SAP Billing and Revenue Innovation Management. The process starts in SAP S/4HANA for Customer Management and ends with the contract and order creation.
The consume-to-cash process starts after the sales and fulfillment processes are completed. The main process steps are charging and rating (SAP Convergent Charging), followed by billable items management, billing and invoicing (SAP Convergent Invoicing). After invoicing, SAP Customer Financial Management ensures a consistent process flow, supporting, among other things, Contract Accounting, Collection Management and Revenue Management.
FI-CA is still the first choice subledger in SAP S/4HANA for industries with high volume and high performance requirements, as well as for service-based scenarios (Utilities, Insurance, Telecommunication).
FI-CA is performance optimized in SAP S/4HANA, but there's no simplification in the data model as done in SAP S/4HANA Finance (Universal Journal, table ACDOCA).
FI-CA and FI Accounts Receivable (FI-AR) can coexist in one system for different customer groups.
FI-CA is highly integrated with other SAP S/4HANA solutions.
