The benefits of the SAP River language (RDL) application development environment were validated by partners and early adaptors. However, based on feedback we received, and consistent with our strategic direction of building open and standard environments, SAP has decided to abandon a proprietary language approach, and to reapply and integrate the SAP River assets and principles within a cloud based development environment as part of the HANA Cloud Platform. The SAP River language will therefore no longer be available as a stand-alone development environment in SAP HANA.
