Answer / manish

LSMW is generally for normal SAP applications, while BDC is mainly for any customized application. LSMW provides various methods for the migration of data, namely, those of direct input, Batch input recording and IDOC. BDC however, simply makes use of recording. There are two ways of implementing BDC, the call transaction method and the session method. In LSMW, mapping is taken care of with the help of SAP, whereas in BDC one has to provide explicit mapping directions. Coding is not very flexible in LSMW, whereas in BDC, coding is very flexible and applications can be easily customized. This is mainly because LSMW is devised specially for functional consultants who do not perform coding, while BDC is mainly made use of by technical consultants, who do perform coding.
