[otrs] how to use otrs tickets types/layouts

hi, i'm little confused, because there are some fields which has own reason to use on incidents, but not usable on problems or general question ticket. I'm looking for something as record type (separate layout on the same object), where each record type should have own layout. this way informations are the same database but not influence users on fields which are not on the right place. is there somenthing similar in otrs ? norbert
