 SAP AG April Accelerating Data Migration: LSM Workbench What is LSMW?

 SAP AG April Accelerating Data Migration: LSM Workbench What is data migration? / Subject of LSM Data transfer  source: non-SAP systems (“legacy systems”)  target: SAP System Initial data transfer from non-SAP systems to an SAP System  Move data from legacy system to an SAP System  Switch off legacy system Periodic data transfer (Interfacing)  Exchange data between an SAP System and other systems Position of data migration  Requires customized SAP System (customizing must be finalized)

 SAP AG April Accelerating Data Migration: LSM Workbench Relevance of data migration?  Accounts for 15% - 20% of the total SAP implementation costs  Smaller implementation projects: up to 40% Why is data migration so expensive?  In many cases you need to develop conversion programs (which can not be used later on) you need to deal with lots of technical details and different technologies data volume depends on the project volume the effort for programming does not depend on the data volume

 SAP AG April Accelerating Data Migration: LSM Workbench What is LSMW (Legacy System Migration Workbench) ? LSMW is a tool based on R/3. LSMW supports periodic and single data transfer from a non- SAP system to an SAP System. LSMW uses standard SAP interfaces.

We are using it for most of our conversions and have found it to be of tremendous help and quality....” “The LSM Workbench saved the day. Without it, we would never have been finished on time.” “...in our opinion, the major benefit is LSM’s flexibility, which allows us to respond very quickly to changing requirements...”

 SAP AG April Accelerating Data Migration: LSM Workbench Examples of positive feedback: “...within two and a half hours, we managed to generate our own migration object for the material master transfer, and successfully migrate the material masters from the EXCEL sheet. It was a complete success!...” “...the transfer of master data on June 12, and of the open items on June 19, 1998, meant that we could go live the same day.” “...I used the LSMW to transfer customers and creditors, and I was really impressed by how fast and flexible it was! Fantastic!...”
