LSMW is a tool provided by SAP in order to UPLOAD huge amount of data from legacy file to R/3 system. The Legacy System Migration Workbench (LSMW) is a tool to transfer data from legacy systems (Non SAP System) into an R/3 System (SAP System).

LSMW supports a step-by-step procedure; if one step is executed and saved then next step automatically FOLLOWS.

Apart from creation of PROJECT/ subproject/ object and recording, there are 14 BASIC steps included in LSMW.

Through LSMW one can create Master data, create transactional data, modify existing master data etc. This tool is very useful when some mass changes are to be carried out and no standard SAP transactions are available for that.

There are few standard objects available in LSMW e.g. material master, vendor master, customer master, purchasing info record, purchase requisitions, purchase orders etc. Using these standard objects one can do mass data upload and mass transactions.

Apart from this LSMW provides another functionality of recording the transaction and then carrying that out MANY times with large data. Examples are mass deletion of purchase requisitions, mass deletion of planned orders etc.
