How to use T-code IW42

Guys,

I checked the forum for any blog or thread on "How to use T-code IW42" but retrieved irrelevant search and no much information on what I am really lookingfor..

Cann anyone explain me in steps how to use t-code IW42 for PM maint order confirmation.

Good movement, confirmation of hours, services and technical completion in steps.

Currently we are using T-code IW41 for manhour confirmation.

Please explain how to use T-code IW42 in detailed steps..
