To recognize revenues either as an event or based on time, SAP developed SD revenue recognition functionality in 2005. Many customers have began using this since then and it has become a stable component. 

SAP ECC based SD Revenue Recognition (Application component SD-BIL-RR) will not be available within SAP S/4HANA. Instead of this functionality, the newly available SAP Revenue Accounting and Reporting functionality should be used. This new functionality supports the new revenue accounting standard as outlined in IFRS15 and adapted by local GAAPs. The migration to the new solution is required to comply with IFRS15, even if no Conversion to SAP S/4HANA is performed.
