DATA Provisioning
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 an ETL tool to transfer data from one database to another database
This tool is the easiest one, to transfer database 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 the source system:
We have three types of sources
- SAP source (ERP, & data Were house)
- Non-SAP (ERP & Non-ERP)
- 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

- system number : ___________
- SAP gateway hostname : _________
- SAP gateway service name : ________
- OK
Go to RFC server interface status (tab)
Select our connection
Click on start

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
