SAP HANA SLT for Oracle DataMarts and SSap R/3

Hi All,

Currently, we have a requirement of pushing the data from couple of Oracle OLTP systems and SAP R/3 systems in SAP BW on HANA system. With Smart Data Access, Can we hit the OLTP systems directly ? Does it create the deadlocks

    Hi Aswini,

    SDA is not a replication production. Smart Data Access is a technology which enables remote data access as it they are local tables in HANA without copying data into SAP HANA. Data in virtual tables cannot be modified i.e. insert, update and delete operations are not possible on virtual tables. However, we can do select on virtual table and put data in HANA table.

    For data replication, you can consider to use SAP SLT, Data Service, HANA Smart Data Integration.

    Regards,

    You do not use SLT for your case. Just use Hana built-in SDA to accomplish it.

      Hi Charles,

      Thanks for your reply. When SDA accesses the source system tables, will the read affect the Transactions being processed on those tables ? Is it better to have a datamart on top of OLTP tables then access via SDA ? If So the real time replication is lost
