We have three types of Replication methods. They are
ETL based
Trigger based
Log based
ETL Based
For ETL based Replication we will use SAP DATA services tools (DS)
DS tool is a ETL tool to transfer data from one data base to another data base
This tool is easiest one, to transfer data base from any database to HANA
ETL – Extraction – Transformation – Load CETL) based data replication uses SAP BODS to load the relevant business data from the source system, SAP ERP, and replicate it to the target, SAP HANA database
Creating data stores for source system:-
We have three types of sources
(a) SAP source (ERP, & data Were house)
(b) Non-SAP (ERP & Non ERP)
(c) File format

Note
To transfer data from SAP BI 
HANA we need t create RFC connection for SAP (BI & DS)
Procedure to create RFC connection
Log on to administrator
Click on to administrator
Select SAP connection under that
SAP service instance
Go to RFC servicer instance configuration (tab)
Click on add provide RFC prog
- RFC program ID : ____________
- user name : _____________
- Password :_______________

- client number : ____________
- system number : ___________
- SAP gateway host name : _________
- SAP gateway service name : ________
- OK
Go to RFC server interface status (tab)
Select our connection
Click on start
Note
After creating RFC connection, we need to create data services source system in BI for 4.0 version SAP has released standard connection for (BI & DS)
Procedure to create Data services Source system in BIs
Log on to BI
Provide URSA 1 (F code)
Go to source system (tab)
Right click on DS(folder) & provide
