BDC is the way to transfer data by writing a batch input program which can use either session or call transaction method.
LSMW used to transfer data without/less code.
What type of data we transfer using LSMW?
LSMW is best suited for transferring master data.
Actually BDC and LSMW are not comparable at all.
for example LSMW itself can use BDC as a way of mass data transfer.
BDC is a mass data transfer technique via screen logic of existing SAP Data entry transactions. It behaves as if you are manually making thousand of entires into sap system as a background job. And that is probably the reason why BAPI's are preffered over BDC's.
On the other hand LSMW is a tool to facilitate DATA migration from other legacy systems ... It contains step by step procedure for data migration.
Like Managing Data Migration Projects , Creating Source Structures , Mapping Source structures wid Target structures , etc etc
LSMW internally might well be using the following techniqes for data transfer..
1. IDOX
2. Direct Input / BDC
4. BAPI's
LSMW is an encapsulated data transfer tool. It can provide the same functionality as BDC infact much more but when coming to techinical perspective most the parameters are encapulated. To listout some of the differences :
LSMW is basicaly designed for a fuctional consultant who do not do much coding but need to explore the fuctionality while BDC is designed for a technical consultant.
LSMW offers different techinque for migrating data: Direct input ,BAPI,Idoc,Batch input recording. While bdc basically uses recording.
LSMW mapping is done by SAP while in BDC we have to do it explicitly .
LSMW is basically for standard SAP application while bdc basically for customized application.
Coding can be done flexibly in BDC when compared to LSMW
reward points if useful
