I am using the class scrbook
and I would like to have parts without prefixes (similar to the default chapters in scrbook), i. e.
\documentclass{scrbook}
\begin{document}
\part{This Is Part One}
\end{document}
Part I.
This Is Part One
should become
I. This Is Part One
I have not found a way to do this in the documentation of koma-script, but I hope there is a simple solution.
