  1. 1. Legacy System Migration Workbench 1 of 74
  2. 2. What is LSMW • It 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 Workbench 2 of 74
  3. 3. General Steps in LSMW • Read 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 Workbench 3 of 74
  4. 4. How LSMW works One or several files Legacy data on PC Read data Read data Structure Legacy data on application relations server Field mapping Convert data R/3 Standard Batch Input Conversion processing rules Converted Direct Input data processing IDoc inbound processingLegacy System Migration Workbench 4 of 74
  5. 5. Step in LSMW • Transaction code : LSMW • 14 steps: – Maintain object attributes. – Maintain source structures. – Maintain source fields. – Maintain source relations. – Maintain field mapping and conversion rules. – Maintain fixed values, translations, user-defined routines. – Specify files. – Assign files. – Read/import data. – Display read/import data. – Convert data. – Display converted data. – Create batch input session – Run Batch input session.Legacy System Migration Workbench 5 of 74
