SAP CUSTOMIZING – TABLE OF CONTENTS
Legacy System Migration Workbench (LSMW) is handy tool for data uploads. In most of the big projects
there is a separate development / data migration team is available. However, at times, it would be
responsibility of the functional consultant to load the data such as vendor master, customer master and
asset master etc. It would be real handy for a functional consultant to know LSMW (at least recording
method) and it would help them to successfully complete the task. Hope this document would help many
of our functional consultants, as I am seeing number of questions around LSMW. The simple rule is:
Follow this document and practice is for number of times possible, then you will become master.
