It is typically used by support staff to maintain / update master data. If your requirement is to complex for Mass Maintenance, then rather use LSMW, it can do even more – but is more complex to use. (Search for posts on LSMW on this site).

Summary of how the process works:

For example: for all materials of type RAW1, make the material group 1012. Lets step through this example to show you how easy it is to use.
