    hi Abhay ,

    the unique differences are,

    Session method.

    1) synchronous processing.

    2) can tranfer large amount of data.

    3) processing is slower.

    4) error log is created

    5) data is not updated until session is processed.

    Call transaction.

    1) asynchronous processing

    2) can transfer small amount of data

    3) processing is faster.

    4) errors need to be handled explicitly

    5) data is updated automatically

    In ‘Call Transaction’, the transactions are triggered at the time of processing itself and so the ABAP program must do the error handling. It can also be used for real-time interfaces and custom error handling & logging features. Whereas in

    Batch Input Sessions, the ABAP program creates a session with all the transactional data, and this session can be viewed, scheduled and processed (using Transaction SM35) at a later time. The latter technique has a built-in error processing mechanism too.

    if its really helpful for u ,pls reward.

    Regards,

    s palan
