[Tex/LaTex] Appendix: Sections without Chapter-Counter

Question

I'm using the documentclass scrbook. When starting the appendix it will give me something like:

A. Some chapter
A.1. Some section
A.2. Some section
A.2.1. Some subsection

The figures will be like A.1, A.2, etc.

I'm looking for a way to remove the Chapter-Counter from the (sub)section-titles in order to get:

A. Some chapter
1. Some section
2. Some section
2.1. Some subsection

While the figures should still be A.1, A.2, etc.

Is this possible?

Answer 1

If you add the line

\renewcommand{\thesection}{\arabic{section}}

immediately after \appendix then you get the output you want.

Here's a complete MWE

% arara: pdflatex
\documentclass{scrbook}

\begin{document}

\appendix
\renewcommand{\thesection}{\arabic{section}}
\chapter{first chapter}
\section{section}
\section{section}
\section{section}
\section{section}
\subsection{subsection}
\subsection{subsection}
\subsection{subsection}
\end{document}
