Hi Experts
We have a requirement that one our customer they are implementing SAP HANA Simple Finance. We will get the data in some sort of files. How to load these data into SAP HANA. Will there be LSMW programs to load the data or we have to exclusively use BODS to upload the data using IDOC’s or BAPI?. Let me know how to start the migration activities.
Currently we are installing PoC system to show to the customer. What all the steps to be followed for Simple Finance data migaration?.

Hi Vijay -
if the data comes in Flat file, then use the Import option in HANA studio to load the files into HANA DB.
You can use BODS as well to load the data into HANA DB.
BAPI & IDOCS exclusively used for to update data into ECC & APO..etc other environments other than BW & HANA.
Hope this helps.

Hi Vijay -
You don't have to write the code to update tables, while importing File it will ask you the Table name and the structure.
you wouldn't be able to use IDOC or BAPI to update data in SAP HANA system.
All this you need to do through SAP HANA Studio where we do all the modeling & views creation..etc
Hope this helps.
Hi Drik
My intention is what all the techniques to load the data into HANA platform. As i am coming from traditional data migration for ECC R/3 i not aware of how to load the data into HANA. In R/3 any migration objects like material master, customer master, vendor master, G/L master we should not update the tables directly. In HANA its opposite to R/3 where tables has to be directly updated. This means i should know all the relevant tables for the particular object. This is what my confusion. How to address this.

Dear Dirk
We have successfully go live on S/4 HANA for one our customer with data migration techniques like LSMW and IDOC methods.
This to every one for better clarity.
The loading technique is same as ECC like LSMW direct input methods, BAPI and IDOC method with same traditional screens and transactions code only advantage is high speed.
Thanks and Regards

Hi Uhdam
We did NOT use BODS itself for simple finance. We use LSMW technique to load the data. We used all sort loading technique like Direct input, IDOC and also BAPI. In our case the volume is less we cannot compare the time taken via IDOC or BAPI.
The suggestion would be if huge volume of data is involved not adviced by IDOC. Go with BAPI where the performance would be much better. If less volume of data then you can use RDS package delivered by SAP which is using IDOC method. Its plug and Play type.
Now its you choice which solution to be implemented.
Thanks and Regards
Vijay
