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.
