ECC to S4 HANA Replication

Hi All

Hope you are all doing well? I am looking to have tables replicated from SAP system with HANA DB to S4 HANA system using SLT.

I am aware of the fact that we need to define a RFC between source and SLT. But from SLT to S4 , do we need to create a DB Connection or is it a RFC

Thanks
