I found an article that Syniti Replicate 10.2 will allow replication from SAP HANA via RFC.
I asked the support team and it seems that only Initial Refresh is supported.
I expect that mirroring will also be supported via RFC connection.
When connecting to SAP HANA via ODBC or NET driver, a Degital Access License is required on the SAP side and a huge additional license fee has to be paid to SAP.
So, if we can get Syniti Replicate to do the mirroring via RFC connection as well, that would be great!
This is already in development and will be shipped within the next quarter.
