Hi Vinay,
SAP LAndscape Transformation(SAP SLT) is one of the data provisioning techniques, used to replicate data from one system to other withing SAP ecosystem. This is popularly used for replicating data from different SAP source system to HANA system, these days. With SLT its possible to have real time data replication into HANA i.e whenever there is change in some data in source system, it will be immediately replicated to HANA with the change and the changed data could be seen in HANA.
