To load data into HANA, SAP offers several options. A real-time replication server called SLT Replication is supported by SAP. You can replicate data from an SAP system or non-SAP RDMS systems such as Oracle, SQL databases to HANA using this server. The knowledge is copied in its native format and must then be de-normalized on HANA using data views (attribute views, analytic views, and calculation views). Besides, Data Services can also be used to transfer data to HANA and can also be used to de-normalize the data, including data quality and cleaning transformations that will help to clean the data before it's loaded into HANA
