2. What is LSMWIt is a interactive tool for data transfer.Data
transfer between legacy system (non-SAP) to SAP once or
periodically.Key benefits: Dramatically reduces the cost and time
of migrating data. Ensure optimum quality and consistency through
import checks.Advantages of LSMW: Wide ranges of data conversion
techniques (fixed values, translation, ABAP coding etc). Conversion
program generated from conversion rules. Consistency in migration.
Less programming required. Platform independent. Check data before
updating in database.Legacy System Migration Workbench2 of 74 3.
General Steps in LSMWRead the legacy data from one or several files
(e.g. spreadsheet tables, sequential files)Convert the data from
source format to target format.Import the data using standard
interfaces ( Batch input, BAPI, IDoc).Legacy System Migration
