    although both are the data transfer tool. but the major difference between both is

    LSMW offers different technique for migrating data: Direct input, BAPI, Idoc, Batch input recording. While BDC basically uses batch input sessions and CALL TRANSACTION method.

    Limit on number of records which can be uploaded in one session of BDC (999 records). No such limit in LSMW.

    LSMW is more to do with configuration while BDC involves programming.

    LSMW can import data from legacy systems (e.g. in the form of Excel sheets or CSV files). I guess LSMW converts your data into batch input files automatically. If you use BDC; you need to write your batch input file yourself, line per line.

    With LSMW, you get a "wizard" (so to say) that writes the batch input for you. It's the difference between writing a program yourself and letting a wizard write it for you.

    But a wizard can only handle some specific situations (Excel file, sequential data in CSV files, for instance) but not ALL situations of data import. For those situations that LSMW cannot handle, you will need BDC.
