What is SAP LSMW ?

The LSMW Workbench is an  tool that supports the transfer of data from non-SAP systems ("Legacy Systems") to SAP  R/3 systems. This can be a one-time transfer as well as a periodic one.

LSMW also supports conversion of data of the legacy system in  numerous way. The data can then be imported into the SAP R/3 system via batch input, direct input, BAPIs or IDocs.

Furthermore, the LSM Workbench provides a recording function that allows generating a "data migration object" to enable migration from any required transaction.



LSMW can be used for following 3 functions -

The main functions of the LSM Workbench are:

  2. Convert data (from source format to target format)
  3. Import data (into the database of the R/3 application)
