SAP LSMW Tutorial
The LSMW (Legacy System Migration Workbench) is a tool based on SAP software that supports single or periodic data transfer from non-SAP to SAP systems (and with restriction from SAP to SAP system). Its core functions are:
- Importing legacy data from PC spreadsheet tables or sequential files
- Converting data from its original (legacy system) format to the target (SAP) format
- Importing the data using the standard interfaces of SAP (IDoc inbound processing, Batch Input, Direct Input)
Generally speaking, ETL (Extract, Transform and Load) is the process in database usage and especially in data warehousing. The LSMW is designed to transform external format to SAP internal format and load the source data into SAP using the standard interfaces. The LSMW doesn’t contain the function to extract data from various source systems. This task can be performed using the third party tools like Informatica.
This page arranges all the LSMW related posts as per below mind map illustrates.
