Hi Shiva
Try considering below methods basing on the nature, volume and usage of the data you need to Upload to R/3 system.
1. BAPI's
2. LSMW
3. Data Transfer Tools(Tran: SXDB)
4. BDC
5. IDoc's
Kind Regards

You can use BDC, LSMW for the transfer of data from non SAP to SAP systems.
The BDC Methods are:
CALL TRANSACTION:
Single transaction can be processed always.
Synchronous Processing - means Transfers data for a single transaction.
Asynchronous and Synchronous Database Update is possible.
No Session Log is created
Faster as it Asynchronous Update is possible.
Returns the SY-SUBRC value.
SESSION METHOD:
Multiple Transactions can be Processed through the same session.
Asynchronous processing - means Transfers data for multiple transactions.
Synchronous updates only possible - means no transaction is started until the previous transaction has been written to the database.
Session log is created.
Slower as it is Synchronous Update only.
Doesn't return the SY-SUBRC value.
LSMW
Legacy System Migration Workbench(LSMW) is a tool for Uploading the Data into SAP.

IDocs
Idocs are Intermediate document created when we transfre data from(legacy system ) to SAP system or within several clients .
ALE (application link enabling) is the medium through which idocs are passed through . Customer distribution model is distributed
BAPI
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
Reward points if useful.

Hi Shiva,
If you are a functional consultant and have to do the transfer without any ABAP help then you can do it using LSMW or SCATT.
Else if you have an ABAP Consultant to help you then you can go for BDC or BAPIs.
Between these 2, BDC is easier.Just do the recording of the transaction using SHDB and ask the ABAPer to create a Report for you.
With BDC method, you are in better position to validate/change the data before posting.
Reward points if you found this answer useful.
