Hi

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

LSMW with TABLE CONTROL

Refer the links -

1. Maintain Attributes:

Here you have to choose the second option and you can do the recording how this should work. Then assign the same to the Batch Input Recording name.

2. Maintain Source structure:

Create a structure name

3. Maintain Source field:

In this you have to create a structure same as that of the input file

eg: name

age

sex

4. Maintain structure relations:

This will link the structure to the input file.

5. Maintain field mapping and conversion rules:

Here is the place where you can do coding, depending upon the code you have written or assignment you have done the values will get picked up from the file and get processed.

6. Maintain field mapping and conversion rules:

If you have any fixed values you can define here.

7. Specify files:

Specify the input file path and type.

8. Assign files:

This will assign ur file to the Input file

9. Read Data:

This will read ur data from teh file.

10. Dispaly Read Data:

You can see the uploaded data

11. Convert Data

This will convert the data to the corresponding format for processing

12. Display Converted data:

13. Create batch input session

Here this will create a batch input session for processing

14. Run Batch Input session:

By clicking on the session and process the same you can do teh needfu.
