1. Session Method(BDC)

2. Call transaction(BDC)

3. Direct input program

4. BAPI

5.LSMW

6.ISMW.

Let me know if u need more details.

Hi,

Data migration can be done by the follwoing methods:

LSMW : for master data migartion or small data migartion

BAPI : its just like a FM , thru which u can create master aswell as Transactional data.

u have to import some paremetre as well as tables if required, and Bapi will RETURN the message saying so and so material/delievry had cretaed.

BDC : in BDC we got 2 methods.

CAll transaction and session.

CAll transacton : using this u can uplaod transcational data as well as master data.

the updation can be <b>synchronus or asynchronus</b> updates.

Session: using this u can uplaod transcational data as well as master data.

The updation in session is <b>synchronus</b>, so its time taking process.

Most of the time we go for Call transcation In real situations.

Dircet input method: its out dated.no longer it is being used.

in all the above cases, data is alraedy existing in flat file and u r going to migrate the data in one shot but IDOC is used where the dynamical data migration is necessary.

suppose say ones the material is craeted in legacy sytem , that particulat matreial shud be migarted to R/3.this can be handled thru IDOC.

Idoc: master data as well as Trnascational data is migarted thru IDOC( matmas, orders).

Idoc uses ALE technology in migartion of idoc.

Revert back if any issues.

Reward with points if helpful
