It could be typo error,
For sap source (on different server) connection has to be created is RFC,
For non-abap connection has to be created is DB from slt replication server.
For step by step refer (note even in this document also at one point there is typo) Step by step procedure for Data replication from Non-ABAP source system to SAP HANA using SAP LT
