Basically data transfer method divided into

1)direct input
2)batch input (call transaction & session method)-BDC
3)BAPI.

Then LSMW is a tool which can be done the above method by
using this tool.

Then LSMW is only for Master data Transfer...i.e Mass data
transfer

For Transactional Data Transfer Better go to BAPI then BDC.

Why bcoz BDC is screen flow logic.. where as BAPI is update
data directly to the data base..
