Hi John,
Yes, SLT can replicate data from a Hana DB to another Hana DB. Hana is among the supported databases as source of SLT.
Then you will have to make this table usable from the application (APO or BW). You can do this on ABAP or, for BW, you can create a virtual provider that allows you to access data from the Hana DB as any other BW infoProvider.
Regards,
Frederic
