Hi,
There is a good blog on LSMW inputs ..
/people/hema.rao/blog/2006/09/14/lsmw--step-by-step
Also for more info refer the below SAP HELP link where all abt LSMW is listed.
http://help.sap.com/saphelp_nw2004s/helpdata/en/7a/5e3d38faba11d1b40f006094b944c8/frameset.htm
With few other inputs,
Direct Input --> This is used when we use the standard SAP programmes for Upload. It updates the related tables directly.
Batch Input REcording --> By means of standard batch input programm...and its more eventful..and can be vouched for in case of any errors.
some Adv :
The LSMW supports a one-time transfer of data (initial data load) and also offers a restricted support of permanent interfaces. Thus, a periodic transfer of data is possible.
Some negatives:
The LSMW, however, does not include any functions for monitoring of permanent interfaces.The tool does not support any data export interfaces (outbound interfaces).
Reward points if helpful

Hi Lokanadh,
LSMW is a tool used to tranfer data from legacy system to R/3 periodically or once.It supports conversion of data and Batch Input,BAPI,IDOC or Direct Input can be used as the method for transfer of data.Total of 26 processing steps are available in LSMW ,In case of data transfer using Batch Input only 14 steps are required.
Execute the transaction LSMW to start transfer of data,Before using the LSMW we should have good knowledge about the business object and the fields that will be transferred.
There are 14 steps that are normally used and these are :
1) Maintain Object Attributes.
2) Maintain Source Structures.
3) Maintain Source Fields.
4) Maintain Structure Relations
5) Maintain Field Mapping and conversion rules .
6) Maintain Fixed Values,translations ,user defined routines.
7) Specify Files .
😎 Assign Files .
9) Read DATA.
10) Display Read Data.

Hi lokanadh
The LSM Workbench is an SAP R/3 based tool that supports the one-time or periodic transfer of data from non-SAP systems ("legacy systems") to SAP systems.
The LSM Workbench helps you to organize your data migration project and guides you through the process by using a clear sequence of steps.
The most common conversion rules are predefined. Reusable conversion rules assure consistent data conversion for different data objects.
