Missing "Appendix" in appendix title when using KOMA-Script class (scrreport)

Question

Problem description:

Recently I moved to the KOMA-Script class

scrreport

to get rid of the

Chapter 1...

extra in the Titles.

This however also changed my appendix to the Format

A. Titlename

Ideally I would like it to look like this:

Appendix A. Titlename

all in one line, or at least get the Chapter format from the report class.

I tried the appendix package like this:

\usepackage[titletoc,title]{appendix}

but this does not seem to work for the scrreport class.

So far I was only able to add an extra page with the word Appendix (in my language Anhang) like this:

\usepackage[toc,page]{appendix}

While the appendix layout looks like this:

%Anhang/appendix
\renewcommand\appendixtocname{Anhang}
\renewcommand\appendixpagename{Anhang}

\begin{appendices}

    %remove entries from the list of figures
    \addtocontents{toc}{\protect\setcounter{tocdepth}{0}}

    \input{Anhang}

    %set it back to 1 otherwise the toc will be missing entries
    \addtocontents{toc}{\protect\setcounter{tocdepth}{1}}

\end{appendices}

Question:

So how can I get the missing word "Appendix" before the ".A" back while staying with the scrreport class ?

Additional Information:

It should also be noted that I do not want the listoffigures to contain anything but the word

Appendix

(in my language Anhang) as you can see when you look at the latex code below.

Minimal working example:

\documentclass[a4paper,12pt,oneside,openany]{scrreprt}

\linespread{1.5}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}

\usepackage[titletoc,title]{appendix}


\begin{document}

%Anhang /appendix
\renewcommand\appendixtocname{Anhang}
\renewcommand\appendixpagename{Anhang}
\begin{appendices}
    \addtocontents{toc}{\protect\setcounter{tocdepth}{0}}
    \chapter{Some apendix heading}
    %set it back to 1 otherwise the toc will be missing entries
    \addtocontents{toc}{\protect\setcounter{tocdepth}{1}}   
\end{appendices}


\end{document}

This will produce (instead of Appendix A):

Answer 1

You need the documentclass option appendixprefix. This alone will not work, because in scrreprt, you have to mark your appendix with \appendix. So in your MWE this would be

\documentclass[a4paper,12pt,oneside,openany,appendixprefix]{scrreprt}

\linespread{1.5}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}

\usepackage[titletoc,title]{appendix}


\begin{document}

\appendix
\renewcommand\appendixtocname{Anhang}
\renewcommand\appendixpagename{Anhang}
\begin{appendices}
    \addtocontents{toc}{\protect\setcounter{tocdepth}{0}}
    \chapter{Some apendix heading}
    %set it back to 1 otherwise the toc will be missing entries
    \addtocontents{toc}{\protect\setcounter{tocdepth}{1}}   
\end{appendices}

\end{document}

This prints Appendix A on a separate line. To get "Appendix A. Titlename" in one line, you can modify \thechapter instead: (You should still use \appendix)

\documentclass[a4paper,12pt,oneside,openany]{scrreprt}

\linespread{1.5}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}

\usepackage[titletoc,title]{appendix}
\begin{document}

\appendix
\renewcommand\appendixtocname{Anhang}
\renewcommand\appendixpagename{Anhang}
\begin{appendices}
    \renewcommand\thechapter{\appendixname\space\Alph{chapter}}
    \addtocontents{toc}{\protect\setcounter{tocdepth}{0}}
    \chapter{Some apendix heading}
    %set it back to 1 otherwise the toc will be missing entries
    \addtocontents{toc}{\protect\setcounter{tocdepth}{1}}   
\end{appendices}

\end{document}

This results in

Too long for a comment.

I'm not sure what is going wrong with your full document. Your example is still very far from "minimal". Take a look at the following simple document and see if it helps you figure out what's wrong with your own document:

\documentclass[appendixprefix=true]{scrreprt}

\usepackage[ngerman]{babel}

\usepackage[toc,page]{appendix}

\begin{document}

\chapter{A regular chapter}

\appendix
\chapter{Some apendix heading}

\end{document}

It produces the following result:
