Step by Step Guide to Upload New Customer Master Record With LSMW
From the material;
The LSM Workbench is an R/3-based tool that supports you when transferring data from non-SAP systems (“Legacy Systems”) to R/3 once or periodically.
The tool supports conversion of data of the legacy system in a convenient way. The data can then be imported into the R/3 system via Batch input, Direct input, BAPIs or IDocs. LSM Workbench provides a recording function that allows to generate a “data migration object” in an entry or change transaction. Through LSMW, we can upload Master Data and Transaction Data.
