Well,

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 .

8) Assign Files .

9) Read DATA.


10) Display Read Data.

11) Convert Data.

12) Display Converted Data.

13) Create Batch Input Session.

14) Run Batch Input Sesion.

Well Kaushal , LSMW is SAP stands for "Legacy System Migration Workbench".

The Legacy System Migration Workbench (LSMW) is a tool recommended by SAP that you can use to transfer data once only or periodically from legacy systems into an R/3 System.

More and more medium-sized firms are implementing SAP solutions, and many of them have their legacy data in desktop programs. In this case, the data is exported in a format that can be read by PC spreadsheet systems. As a result, the data transfer is mere child's play: Simply enter the field names in the first line of the table, and the LSM Workbench's import routine automatically generates the input file for your conversion program.

The LSM Workbench lets you check the data for migration against the current settings of your customizing. The check is performed after the data migration, but before the update in your database.

So although it was designed for uploading of legacy data it is not restricted to this use.

We use it for mass changes, i.e. uploading new/replacement data and it is great, but there are limits on its functionality, depending on the complexity of the transaction you are trying to replicate.

The SAP transaction code is 'LSMW' for SAP version 4.6x.

For those with the older SAP version (4.7 and below), the data migration programs might not have been pre-loaded.

You can download the LSMW at no cost from SAPNet under Services, SAP Methodology and Tools, category Tools.

If you are an existing SAP customer with an OSS ID, you can access the SAP Service Marketplace to download the LSWM for your Basis teams to install to your SAP system: http://service.sap.com/lsmw

The LSM Workbench carries out the following tasks:

1) Reads the transfer data from one or more files (for example, spreadsheets, sequential files etc.)
2) Converts the data from the source format into the target format
