In a SAP Insider blog published on February 11th, Karl Kessler, SAP Vice President of Product Management for the ABAP Platform, describes the new release strategy for the ABAP Stack that will come into operation as of the 1809 release of S4/HANA.
The main takeaway is that all innovation effort will be focused exclusively on SAP S4/HANA. For the SAP Business Suite and SAP NetWeaver codeline, which is based on SAP NetWeaver AS ABAP 7.5x. improvements will continue to be delivered (such as maintenance efforts, security fixes, and selective downports) but no new functional innovation will take place. This effectively means that SAP Business Suite, which will be supported until 2025, is to become a "mature" product.
