What is the difference between LSMW and BDC?..

Answer / anwar

BDC is Batch Data Communication. It is basically a program
either generated by SAP after a recording or programmed by a
abaper.Its like running the transaction manually but all the
data is populated on the screens automatically.It is a
little complex when the screens contain table controls.
LSMW is legacy system migration workbench is a more user-
friendly tool thru which one can do the same as a BDC. One
just has to follow some 14 steps, click buttons and the data
is set to be uploaded ….LSMW offer you 4 ways to import data
into SAP, they are BDC, Direct Input, BAPI(BO), IDOC.
To spell out the differences in detail:

Answer / mahender achhe

LSMW : Legacy System Migration Workbench.
BDC : Batch Data Communication.
LSMW : It is used for migrating the data b/w the Non-SAP
and SAP application to do for that we can take the Non-SAP
application data and Converts the data into the Legacy data.
(Legacy data means Cleansing data and Purging the data
After the Legacy data creation convert the data in to
the "Flat file". That flat file is in the form of text file
or excel format.If the file is in the form of text format
we can create the ".txt" file ("ABC.txt")and in the form of
excel ".xls" file is created. flat file for dos and .xls
file for IBM.
The converted file (.txt/.xls)is either upload or download.
The Upload functionality if used for .txt file to SAP and
where as Downloading is the concept while SAP to .txt/.xls
file.
BDC : It is also used for migrating the b/w the non-sap to
sap applicatios.

in lsmw below 5000 records are updating or inserting
purpose we can use the lsmw.but where as above 5000 records
are uploaded we can use BDC.

What is the difference between LSMW and BDC?..

Answer / priyanka j

BDC and LSMW both are tools to transfer data from non-sap
to sap syatem and vice-versa.

LSMW contains 14 steps available in radio buttons that
directs you and takes you to the end of the process where
the data is transfered, tcode --> lsmw.

BDC has two methods 1. Call transaction method ; 2. Session
method. Here we need to write code to accomplish the
process or we can record steps of a certain process like
ex: creating a table with se11. Tcode--> SHDB and sm35
resepectively.

Amongst the two BDC is preferred more than LSMW as there
are more chances of errors in lsmw.

good method to transform data .

What is the difference between LSMW and BDC?..

Answer / honey deep

In BDC (Batch Data Communication) to upload the flat file
into one SAP system from another SAP system or non SAP
system , we can apply the validations by coding . Hence we
can modify it according to our needs.

BDC is developer made method while LSMW is provided by SAP
directly and hence u dont need to code anything, just need
to follow those 14 steps in order to upload the flat file.
Hence u cannot make the validations in LSMW.

In BDC , u can even schedule the job , so upload can be done
in once or later periodically while in LSMW it has to be
done in once only. So, through LSMW, one cannot upload huge
amount of data.
