Hi Anindya:
I contacted Emily Rakowski, who leads SAP and Ariba Procurement Marketing. She provided the following guidance for your question:
“SAP SRM remains the solution of choice for SAP customers that want an on premise option for eProcurement, or who need more extensive integration to SAP ERP. With many thousands of productive customers on this solution, SAP will continue to support this solution including incremental improvements. In 2013, the SAP SRM User Interface Add-On became generally available as the new shopping interface with a new Amazon-like experience for customers. Additionally SAP SRM was adapted to run on HANA for faster and more reporting options. Additional improvements on the roadmap for SRM are listed in the publicly accessible roadmap on SAP Service Marketplace.”
