Landscape + Longtable + Section heading

Question

i have a problem to get the section heading on the same page as my table. Any idea to solve this problem? Here is my (shortened) code:

\documentclass[a4paper, 12pt, twoside=true, openright, headsepline, pointlessnumbers]{scrbook}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english,ngerman]{babel}

\usepackage[backend=bibtex,style=alphabetic]{biblatex}
\addbibresource{citavi_lit.bib}

\usepackage{longtable}
\usepackage{lscape}
\usepackage{booktabs}

\begin{document}
\section{Test section}
\ref{tab:test} is a landscape longtable
\begin{landscape}
\begin{longtable}{lll}
    \caption{test}\\
    \label{tab:test}\\\toprule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    1           & 2             3            \\\bottomrule
\end{longtable}
\end{landscape}
\end{document}

You need to make sure that the table is not so wide that there is no room for the section head, but if there is room you can position a heading in the space, if you need that

\documentclass[a4paper, 12pt, twoside=true, openright, headsepline, pointlessnumbers]{scrbook}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english,ngerman]{babel}

\usepackage[backend=bibtex,style=alphabetic]{biblatex}
\addbibresource{citavi_lit.bib}

\usepackage{longtable}
\usepackage{lscape}
\usepackage{booktabs}

\begin{document}

\begin{landscape}
\begin{picture}(0,0)
\put(550,10){\rotatebox{-90}{\parbox{5cm}{\section{Test section}}}}
\end{picture}
\begin{longtable}{lll}
    \caption{test}\\
    \label{tab:test}\\\toprule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule
    \textbf{1}  & \textbf{2}    & \textbf{3} \\\midrule

    1           & 2             3            \\\bottomrule
