Hi Venkat, the short answer is: Yes, we will continue to support connectivity to SAP.
Our connectors install and run on BW 7.5 and we are currently evaluating BW/4HANA. However, there are no dedicated connectors to the new BW objects such as ODP, CompositeProviders etc. The data is usually available through the SAP SQL Connector, BEx Connector (some limitations on new functionality exist) or any of the other SAP Connectors that we offer. There is also the possibility of exposing the BW objects as HANA view and access them through the ODBC connector. We are continuously improving our connectivity options to SAP and you can expect more dedicated BW 7.5 and BW/4HANA connectivity in the future.
